DWDM SFP modules - where to use?

Hi, we are considering to interconnect two sites using DWDM. What type (colored, non-colored 1310) SFP modules should we use on our switches connecting to multiplexer/OADM? Does it depend on the actual MUX device?

DWDM multiplexers and OADM filters have wavelength specific ports, that are connected to an optical transceiver of the same wavelength. Below is a link to the Cisco DWDM pluggable optical transceivers,

The difference between ONS-SC-2G and DWDM-SFP

Our datacenter needs to summary 6 wavelength from the sub-datacenters. All sub-DCs need to communicate with our DC. We have 6509E,15216 MUX/DEMUX and 15454-SA-HD=.
Wavelength list:
DWDM SFP 1535.04 nm SFP (100 GHz ITU grid)
DWDM SFP 1534.25 nm SFP (100 GHz ITU grid)
DWDM SFP 1532.68 nm SFP (100 GHz ITU grid)
DWDM SFP 1531.90 nm SFP (100 GHz ITU grid)
DWDM SFP 1531.12 nm SFP (100 GHz ITU grid)
DWDM SFP 1530.33 nm SFP (100 GHz ITU grid)
Which SFP module do we need to use in our datacenter?
For example DWDM-SFP-3033= and ONS-SC-2G-30.3=. Which should we choose?
Which board should they be inserted and working on?

Hi,
- Do you have any design CTP file?
- Are you already have channels betwen DCs?
This modules have same specification, but different hard-coded part number inside.
Spec for DWDM-SFP-XXXX=:
http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/dwdm-transceiver-modules/product_data_sheet0900aecd80582763.html
Table 2. Optical Parameters
Spec for ONS-SC-2G-XX.X=:
Table 29. CWDM SFP Modules: Optical Specifications
Table 30. DWDM SFP Modules: Optical Specifications
Table 31. DWDM SFP Modules: Optical Performance
Now you can see that they are the same specification.
- If you will use DWDM-SFP-XXXX= in ONS chassis it will work BUT in CTC you will see alarm "Provisioning mismatch".
- If you will use ONS-SC-2G-XX.X= in ONS it will work fine.
- If use ONS-SC-2G-XX.X= in 6k it will work, but you should use DWDM-SFP-XXXX= in 6k Catalyst and connect it directly to 15216 MUX\DMX if distance short. Need CTP design file to check it.

SFP Module Question

Does anyone know if a GLC-T SFP module can be used in the ge ports of a SN 5428 storage router?

The GLC-T may work. I never tried it and I never heard of anyone using RJ45 into the GE ports. Even if it did work, the bottom line is it is unsupported. We only support the short wave and long wave fiber SFPs,
DS-SFP-FCGE-SW
DS-SFP-FCGE-LW

SFP module, help

Hi guys,
I never use SFP module before, so please help me out.
I have a fiber connection between location A and B. I test the fiber with contractor and the result is successfull.
From the termination, there is patch cord that connect to a SG 300-10MP 10-port Gigabit Max-PoE Managed Switch (SRW2008MP-K9-EU) using a SFP module (MGBSX1).
Location B also the same. From the termination, there is a patch cord connect to a 3Com switch also using a SFP module.
My question is, at the Cisco switch there is no green indicator light, and is check the GUI it show port is Adminstrative = UP, Operational = Down.
If connect the termination to the SFP, it should have light right??
Fyi, at the 3com also no light indicator.
I need an opinion.

Do you have multimode fiber between Location A and B? How long is this fiber link?
What SFP module are you using in the 3COM swtich?
If you take a patch cord and loop it at Location A from the SFP's transmit port directly to its receive port, does the GUI show UP, UP? Try the same at Location B. This should confirm the SFPs are working.
The following 2 documents can be helpful troubleshooting transciever and link issues.

ABAP Function Module where-used in BI-Transformations

Hi,
we have developed some ABAP-Z-Function-Modules. These are used in several BI-Data-Transformations and work fine and performant.
The problem we have now is to find out in which transformation a Function-Module is used.
The where-used-list in SE37 doesn't report any BI-Transformations althought I check all categories.
Got anyone a solution for our problem?

Cisco 2960S-24TS-S using SFP modules between switches

I am using Cisco 2960S-24TS-S using SFP modules for two different speed requirements, I have two SFP ports using 100Mbit modules and the other two SFP ports using 1000Mbit modules.
I have two Cisco 2960S-24TS-S switches connected together via a fiber optic cable, and each SFP module is on port 28, with a 1000 Mbit SFP module in each, and the two switches will not connect. The fiber was checked with a light tester not a db kit.
Do I need to have SFP port specific setup details in a configuration file for the Cisco Switch or does the SFP module handle this?
" interface GigabitEthernet1/0/28" - set up in config file for the port. Does this need to dictate "interface 100" or "1000MbitEthernet1/0/28" instead?

The ports should auto-negotiate speed you should not need to hard code them to get them to come up , Are the ports showing up/down or down/down can you post the show interface for each side and the show run int x/x for each port

Optical Fiber connection between GBIC module and SFP module

Hi
I am in need of help.
I have a 3750 24TS-S, 2 port SFP, switch at the edge. And i have a 4507R switch at the Distribution layer. In 4507 switch I have WS-X4515 Sup IV supervisor engine with 2 GBIC Port and also have WS-4306-GB 6 port GBIC module. I am using WS-G5486 Single mode connector, LX/LH tranceiver to connect to this port.
This is the scenario.. i want to know is it posible to conect one end of the fiber cable to connect to a SFP Module ( 3750-24TS-S, 2 Port SFP) and other end ( WS-X4515 Sup IV supervisor engine with 2 GBIC Port or WS-4306-GB 6 port GBIC module) at the WS-G5486 Single mode LX/LH connector ?????
Plz let me now asap.. i need to give a solution imdtly.
Thanks & regards
Jacob

Discussion is never a problem ....;-}
The issue is that the signal is "too loud" and is distorted (or, more correctly, is so loud it overloads the receiver).
The operational envelope for nearly every receiver of any kind includes a bottom number (too weak to hear) and a top number (too loud to understand).
As an example, think about an system where you have a hearing aid that would let you hear someone speaking in a normal voice from 100 feet away ... then having someone scream the same words into the hearing aid from 6 inches away ... the sound would be distorted and you would have difficulty understanding them ... after a while, you'd begein to go deaf and eventually, it would sound normal (until you became completely deaf).
So, what you need to do is look at the transmitter power, and the envelope/range of acceptable power the receiver can hear.
Normally that difference is the optical budget ... given the loss numbers of the media between the two, you can determine if you have enough power to make the trip.
In a Lab environment, you still have to hit the receiver's budget number, but from the other end (the "too high" side).
If you know the transmitter puts out X, and the receiver can accept from Y to (X-50), then you need to add enough attenuation to get X down to (X-50)or lower (but still more than Y).
When you have a transmitter powerful enough to drive tens of kilometers, putting one two meters away from the receiver will pretty much guarantee a burnout (unless you install optical attenuation).
Good Luck

C2960-S SFP Module not active

I have set up Cisco switches previously via the hyperterminal and been able to get them configured and operating, but I have limited knowledge of the tools and processes.
I have a 2960-S with 48 ports and 4 SFP modules.
I have good feedback on the 48 ports, but I can not get the SFP modules to ether be recognized or show any activity on the 2960-S. The unmanaged switch I have the fiber connected too, is indicating a network connection and activity, but the 2960-S is not indicating any connection on the SFP modules.
I have added the switch configuration file.

Ok. I see you posted your config above, and after reading a bit more here, you're dealing with layers 1-2 of the OSI model at the moment, so let's focus on that. For your unmanaged switch, are you using the same type of SFP? Sometimes you need to use the same on both sides for a link to come up. I have tried off branded + Cisco before and it had lots of problems. Also
If that is not the problem, I would say look over your running-configuration for port 49. It does not appear to have any configuration added to it so far. If every device on your unmanaged switch will be on the same vlan, you can turn port 49 into 'switchport mode access' and 'switchport access vlan 1' as well as 'spanning-tree portfast'.
If not all devices will be on vlan 1 on your unmanaged device, you can try 'switchport mode trunk'. This will allow vlans 1-4094 across by default (you can limit this too). Make sure that the unmanaged switch is set to trunk mode as well, and allowing the vlans you want across.
For troubleshooting, you can try 'show spanning-tree vlan <xxx>' where xxx is the vlan you are having trouble with. Lastly, you can also try to issue a 'show interface gig 1/0/49 counters detail', which will show you all the types of packets entering the port. This varies from ios version to ios version, but it will show unicast, multicast, broadcast, packets below the MTU or above (runts and giants).
I hope that helps : )

SFP module strange behavior

The strange thing about it is that when observing transiever status I see the flap of that kind:

Gi6/1       0.7       0.01 --    0.3 --   N/A ++ -40.0
I could guess that this is the power problem, perhaps sfp module installed badly or the transmitter is out of service.
But..the magic is that the interface is operational, trafic flows and no threshold messages are dropped into log:

So...is it some bug with all finisar modules, or it is a module frome a corrupted production set, or it is an IOS bug of "sh interface transiever" command ?
Any ideas?
Thanks in advance.

From my post it is evident that I use either SM or MM capable trnasiever (1000BASE-LX/LH)
My trnasiever is anyway operational though indication is incorrect.
Perhaps, you (and I) should look for other than Finisar transiever vendor, compartible with cisco
Look for where the transiever was manufactured. Better it is Japan, not Malayasia or China.

SFP module not showing up as interface choice

I am trying to configure a 3825 router w/IOS 12.4(3d).
When I install a GLC-SX-MM module, I cannot see the module in the sh diag results and therefore not a choice in the list of interfaces.
When I view the logs, the insertion is logged.
Any assistance would be greatly appreciated,
Chris

Hi Chris,
There are two Gigabit Ethernet ports on Cisco 3800 Series systems. Port 1 is a fixed 10/100/1000BASE-T RJ-45. Port 0 can choose between 10/100/1000BASE-T RJ-45 and an SFP module slot. SFP modules are optional.
A new command-line interface (CLI) allows you to choose between the two media types. The "SFP" option will only come up if there is a SFP module plugged into the slot. RJ-45 is the default.
Please see the following configurations to get this port working:
Cisco3825#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Cisco3825(config)#interface gigabitEthernet 0/0
Cisco3825(config-if)#media-type ?
rj45 Use RJ45 connector
sfp Use SFP connector
Cisco3825(config-if)#media-type sfp
After this you should be able to use and see the SFP on the router. Hope this helps. :)
Regards,
Param

FAS2554 UTA2 Ports SFP+ Module requirement

Hello, Have anyone know the Netapp FAS2554 UTA2 Ports have any specific requirement for the SFP+ module?(I means if I purchase one other brand SFP+ moudule, it is possible to comptiable with UTA2 ports?) Thanks in advanced!

Hi, From Hardware universe : The onboard UTA2 ports can be configured as FC Target/Initiator or CNA (FCoE target/Ethernet). The UTA2 ports are based on a dual port ASIC and both ports on each ASIC must be set to the same mode (enforced by Data ONTAP). Install X6589-R6 10GbE SFP+ modules or approved copper twinax cables when using in CNA (FCoE target/Ethernet) mode. Install X6596-R6 16Gb FC SFP+ module when using in FC Target/Initiator mode. Thanks

Hi:
You may want to post your question on the HP Business Support Forum -- Switching section.
http://h30499.www3.hp.com/t5/Switching-and-Routing/ct-p/switching

Choosing correct optical patch cable based on SFP module

can someone share information regarding the topic (all cable parameters should pass to a certain SFP module: connector type; mode type; diameter etc)?

Ok, so you'll need a patch cord of the following specifications:
<LENGTH> - You choose whether you want pre-made 10 metres or you can get them to customize the length (will cost more, obviously).
Terminating end types - LC to LC (Duplex);
Multi-Mode optical fibre;
OM4 - You can use OM3 if you want but I'd rather use OM4. Don't even attempt to try OM1 or OM2.
<COLOR>- Your choice. Normally, OM4 is aqua but you can choose any color you want (may cost more). DO NOT USE YELLOW as this means a different type of cable (single-mode). You do not want to make your fibre optic cabling confusing for everyone.
NOTE: If someone wants to sell you an "angle cut" multi-mode fibre, they need to be taken out and shot.

Disabled GBIC SFP module

I have 2 WS-3750-48PS switches in a stack, i have today installed 2 x MGBSX1 sfp's to link new fibre to other building on the grounds.
I have now got 2 types of error messages showing :-
EVENT NOTIFICATION -
Description: Gi1/0/3: This port has been disabled because Non Compliant Gigabit Interface Converter (GBIC) connector detected.
Recommendation: Replace connector with cisco compliant Gigabit Interface Converter (GBIC) connector. Refer switch technical documentation to determine cisco compliant connector. Enable the port again.
SYSTEM MESSAGES
unfortunately i haven't got the full message but it was saying thet there was a CRC error in the EEPROM and that maybe a software update would rectify the problem.
The stack is running 12.2(35)SE5-IP-BASE software at the moment and i have seen on a Cisco page that ALL cwdm sfp's are compatible with my switches (http://www.cisco.com/en/US/products/hw/modules/ps4999/products_tech_note09186a00807a30d6.shtml#support3)
Should i upgrade the software to 12.2.55-SE3 ?

The reason for the Non Compliant error message is that the MGBSX1 sfp is not a "compatible" product with the WS-3750-48PS switch, per the following compatibility document:
http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.html#wp137837
According to the document you referenced, the following statement may be the reason you are receiving CRC errors on the port.
"Use Third Party SFP Modules
The use of third party SFP transceivers with Cisco devices is not supported by Cisco. Cisco-approved SFP modules have a serial EEPROM that contains the module serial number, the vendor name and ID, a unique security code, and cyclic redundancy check (CRC). When an SFP module is inserted in the switch, the switch software reads the EEPROM to verify the serial number, vendor name and vendor ID, and recomputes the security code and CRC. If the serial number, the vendor name or vendor ID, the security code, or CRC is invalid, the software generates this security error message and places the interface in an error-disabled state."

SG500 5Gb SFP module

Hello,
I was wondering what fibre SFP module I use to stack SG500 switches at 5Gb.
In the datasheet it says SFP-10G-SR can be used for 10Gb stacks with SG500X switches but doesnt say if it can or can't be used on the SG500.
I am using mulitmode fibre and the distance is less than 200m.
Thanks.

Hi David, yes you are right I have neglected the fact it is twinax. It is also correct about fiber. The problem will remain an actual distance.
The copper modules will work perfectly fine for the 5 gig slots up to the available wire length. A 1 gig fiber module such as MGBSX1 would be a suitable 550 meter or less multi mode solution if the distance does exceed the length of the copper or ethernet.
However, what is not clear is a factual distance. Less than 200 meters is ambiguous and there are 3 correct answers. If this is within 30 feet let's say then the 5 gig is by far an exceptional choice. If it will be outside of the 30 feet then another solution such as a multimode fiber using MGBSX1 will do the trick for a 1 gig link for 550 meters. Also running regular Cat6 can also do this trick for less than 100 meter. Or for a different approach, MGBT1 using Cat6 which is an ethernet module.
It is just a matter of having all information since the ONLY distance mentioned is less than 200 meter. Perhaps I could do better and first ask "How far are you truthfully going"? or "Here's 3 options..."
