XENPAK-10GB-LX4 and X2-10GB-SR

Hi all, has anyone connected a FO using 10GB-SR and a XENPAK-10GB-LX4 gbic, could we have a problem if we do so for a cable distance of 80 to 120 meters.
thks in advace.
Mario

X2-10GB-SR transceiver module for MMF, 850-nm wavelength, SC duplex connector while the 10GBASE-SR X2 transceiver module for MMF, 850-nm wavelength, SC duplex connector supports link lengths of 300m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met, the transmitter output should be coupled through a mode conditioning patch cord. For additional information on mode conditioning patch cord requirements please see: http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html.

XENPAK-10GB-LR+ not showing Proper product ID

Hi Experts ,

Both Switches have same SUP "WS-SUP32-10GE-3B" only difference I see is IOS ,but I am not finding any documentation that says IOS is causing the switch to show incorrect Product ID .
Services are working fine.

Sounds like you are getting some data, jut not performance data(?) so I would not suspect the agent.
Check your binaries on the agent - you should have 2 or 3 with root permissions and the sticky bit turned on.
Make sure you have the new port numbers being used since the agent should now be connecting via the secure port (this looks to already be the case from your post)
Hit the url from the web browser:

Any firewalls between you and the oms?
Does the agent know the oms dns/ip?

Allowable path loss between Cisco XENPAK-10GB-LR & HP BLc 10Gb

Greetings All!
How much attenuation loss should be allowed (upper & lower range) for 10Gb link between Cisco XENPAK-10GB-LR & HP BLc 10Gb?
Thanks.
Regards,

Well the Cisco XENPAK 10GB-LR is spec'd for spans up to 10 km.
Per its data sheet, the transmit power ranges from +0.5 dBm max down to -8.2 dBm min. Receive levels must be no greater than +0.5 dBm and no less than -14.4 dBm.
The HP BLc 10GB (assuming it is the LR type transceiver) does not have any such detailed specification that I could find.
I'd estimate worst case planing would would be the difference of the minimum Cisco Tx and the least allowable Rx power = 6 dB loss end to end. When in doubt, measure it!

CISCO XENPAK-10GB-LW (WAN PHY)

hi,
do you know if installing the CISCO XENPAK-10GB-LW (WAN PHY) you need a SONET/SDH multiplexer or you can connect it directly to the SDH network?
any document explaining it?
thanks

The WAN PHY module will appear to your SDH network as a SONET tributary interface. Its signal will need to be carried intact as an OC-192 (approximately 10 Gbps) across the SDH network since it's not a bunch of STS payloads but rather a single 10 Gbps IP stream encapsulated in SONET framing. Other than that, it should be able to feed your SDH network's ADM just fine (given attention to your optical power levels, etc.).
Hope this helps, please rate helpful posts.

X2-10G-LX4 and SFP-10G-SR

Hi
Issue 1
I have a 6506-E with WS-X6708-10Gig Modules and i have installed X2-10G-LX4 transceiver on them, on the other side i have a UCS 6120 and installed a SFP-10G-SR.
The link between the 2 does not come up, what could be the reason for that? The distance between the 2 is 10 meters and i have already tried changing the cables.
Issue 2
If i connect the WS-X6708-10Gid module with X2-10GB-LR module and connect it to X2-10GB-LR on another 6506-E, the link comes up. that means there is no problem with the Module or the ios on the switch.
but if connect X2-10GB-LX4 on 6506-E and X2-10GB-LX4 on the other side, the link does not come up. Any clue what could be the reason ? I have already tried changing the transceiver.
Can someone please help ?

issue 2

You have got answer for first issue that LX4 cannot work with SR. By the way what kind of fiber you have Single Mode/Multimode?
second issue,
If your X2-10GB-LRmodule have worked then i can assume that you have single mode fiber for testing as LR is only for Single mode fiber .
LX4 is only made for Multimode fiber and it is not going to work on single mode fiber no matter what you try (as you are saying link is not comming up).
Cisco X2-10GB-LRM is the only module which can work for Single mode and Multimode (ofcourse you need Mode conditioning patchchord )

Cisco XENPAK - HP2910 10GB interface

Hi,
We need to connect a Cisco XENPAK-10GB-LR module with a "HP ProCurve 2-Port 10-GbE SFP+ al Module (J9008A)" (a module inside a
"HP Switch E2910-48G al(J9147A)")
The HP switch module would have an "HP X132 10G SFP+ LC LR Transceiver (J9151A)".
Where can I find some info if this kind of fibre connection is supposed to work ?
The specifications for both the devices (XENPAK and the HP module/tranceiver) are same - 10GBASE-LR (single-mode fiber, 1310 nm).
Regards,
Florin

Yes, the two transceivers will interoperate.
Make sure you order the correct singlemode fiber patch cords to interface to the LC/UPC connector type on the HP transceiver and the SC/UPC connector type on the XENPAK.

Connecting Xenpak LX4 to SFP+

I am looking at deploying the 4948E switch in my enviroment to replace a 6504 with Sup720 10gig blades. The 6504 is using the XENPAK-10GB-LX4 to connect to my core and the core is using the same Xenpak. I don't want to replace the Xenpaks in my core if I don't have to.The 4948E uses STP+ and there isn't an SFP+ LX4 module. It looks like the XENPAK-10GB-LX4 should connected to the SFP-10G-LRM. Am I correct?
Steve

"It looks like the XENPAK-10GB-LX4 should connected to the SFP-10G-LRM. Am I correct?"
You cannot connect the LX4 to the LRM.
The LX4 actually transmits 4 optical signals (parallel) versus a single optical signal (serial) for the LRM. The following Cisco paper discusses the LRM and LX4 interfaces.
<http://www.cisco.com/en/US/prod/collateral/modules/ps5455/prod_white_paper0900aecd806b8bcb.html>
Unless you can use an 4900 module that uses X2 optics modules with LX4 support, you will have to select another module type for your core switches.

C3-XENPAK10GB-LR and XENPAK10GB-LR

Hi,
My switch is WS-C3750G-16TD-S.
I add a 10GE module - XENPAK-10GB-LR=.
But per Cisco's document, I should use XENPAK-10GB-ER or C3-XENPAK10GB-LR=.
My question is if I can use 'XENPAK-10GB-LR'. Is there any difference between 'XENPAK-10GB-LR' and 'C3-XENPAK10GB-LR'?
my other side switch(4506) run with 'X2-10GB-LR='. Now my problem is the traffic which pass the 10G link is always limited in about 300Mbps.
Thank you all for any advice.
Regards,
Sha

Hi
AFAIK the main difference between the LR and ER is similar to the kinda of LX or ZX in SFPs.
It differs basically on 2 things like the wavelength it uses and the distance in km which it can support or drive the signal.
from my personal exp we do connect the equipments on the same kinda module on both the ends instead of putting into 2 different modules on both the sides.
attached links has the wavelength,fiber patch cord mode and also the distance supported by the respective modules ,also find the compatibility report released by cisco on this 10G modules

10 gig fiber tranceivers

Hello all,
My question is based on the info found at http://www.cisco.com/en/US/prod/collateral/modules/ps2797/ps5138/product_data_sheet09186a008007cd00_ps5455_Products_Data_Sheet.html
According to this doc if I have multimode 50 micron fiber with a modal bandwidth of 2000, I can use the XENPAK-10GB-SR for a distance of up to 300 meters. Because my fiber has this type of modal bandwidth, does this mean that this optic is my only option? Can I not use the XENPAK-10GB-LX4?
Thank in advance.

LX4 module is fairly expensive so you would probably want to use the SR module
cisco is not supporting it but standard LX4 is a low power single mode transmitter and preferred by guys who thinks that they need a sigle transmitter for MMF & SMF. TiIl 2005 they were cheaper than 10GBASE-LR which is a
single mode laser.
http://en.wikipedia.org/wiki/10_gigabit_Ethernet
To use LX4 with MMF a mode conditioning patch chord is used. A mode conditioning patch cord is a short length of SMF which connects to the MMF in such a way to move the beam away from the central defect in the legacy MMF.

Cisco ASR1001-X SFP-10G-SR: unable to bring 10G port up

Dear colleagues,
I have connected a Cisco ASR1001-X 10G port to a 10G port on the Cisco 7606-S. The SFP on my ASR1001-X is SFP-10G-SR and the SFP on the 7606-S is XENPAK-10GB-LX4. I am using an MMF fibre patching. I am unable to bring the port up. I have a temp license for the ASR 10G port. Is that sufficient to bring the port up?
I have tried connecting the SFP-10G-SR to a XFP-10G-MM-SR on another ASR but this did not work either. I am able to connect the XFP-10G-MM-SR to one another and also the SFP-10G-SR to one another. So there appears to be an issue when I mix the SFPs.
Can any one help please?

Unusually low Rx power values ? WS-X6704-10GE (10Gbase-SR)

Referencing...http://www.cisco.com/en/US/prod/collateral/modules/ps2797/ps5138/product_data_sheet09186a008007cd00_ps5455_Products_Data_Sheet.html
The Optical Transmit and Receive Specifications for this transceiver (XENPAK-10GB-SR) indicate :
Tx Power (dBm) : Max -1.2, Min -7.3
Rx Power (dBm) : Max -1.0, Min -9.9
We are seeing readings on one of these modules that are clearly well outside these ranges.
Tx Power (dBm) : -18.6
Rx Power (dBm) : -40.0
No interface errors or anomolous behaviour of any kind is indicated on this interface at this time.
My question.
Without getting into the detail of what could be the potential cause of this particlar interface showing these readings (as all of the other interfaces are reading within the specified range), could I get an opinion as to what impacts, if any, we can expect to see on this interface as a result of these observed values ?
Thank you for your inputs.

Tx power is measured from this XENPAK and must be inside the specified range. -18dBm is around 32 times less than expected. I would consider this XENPAK as broken and replace it as such strong power difference can cause errors on a receive side.
Rx power range is what is expected from the remote end. Measuring Rx power makes sense when there is something transmitting light to us and we want to confirm an incoming power does not exceed our Rx power range.

6509 to ons 15454 showing not connect.

Were running into a problem moving from an oc48 to oc192. In our web enviornment we have a Front-end switch and a Back-end switch in two data centers that are 10 miles apart. Were running a "gigaman" betweent the two. On both ends we have cs6509's and were patched into the Gbic interface on the sup2's. This fiber is ran to are lec's ons 15454 which I have no visibility into. We are unable to get a connection on the 6509's. Were doing basic layer 2 trunking between the switches. Sbc tested from the fiber on the switch to a loop on the other switch and was able to test clean. This worked on the oc-48 but are switches were not connected to a cisco ons. Any suggestions would be apperciated. You can also email me at [email protected] or AIM jjt8572.

Have you checked that you have matched the physical media framing - e.g., LAN PHY needs to speak to LAN PHY (or WAN PHY to WAN PHY). Typically the ONS 15454 would be looking for a SONET frames (WAN PHY) while a Cisco 6509 would be sending 10 Gigabit Ethernet LAN frames (LAN PHY). That is, unless you specifically choose an interface for your 6509 such as the XENPAK-10GB-LW (10GBASE-LW XENPAK Module with WAN PHY for SMF). From that product's data sheet: "The Cisco 10GBASE-LW Module supports a link length of 10 kilometers on standard single-mode fiber (SMF) (G.652).
WAN-PHY is intended to allow the transport of 10 Gigabit Ethernet over a traditional SONET/SDH infrastructure. The purpose of WAN-PHY is to render 10 Gigabit Ethernet compatible with SONET STS-192c format and data rate, as defined by ANSI, as well as the SDH VC-4-64c container specified by ITU."
One can also use Cisco ONS transponder cards that will wrap LAN PHY framing in something like G.709 encapsulation to allow it to be transported through a DWDM network.

VSS Reconfiguration on Catalyst 6509

Hello Team,
I would like to know about the reconfiguration of VSS on Catalyst 6509. VSS is already running but we need to reconfigure it on other ports.
Currently Its is running on the VS-S720-10G Supervisor 2x10-G ports but we need to reconfigure it on other 10G ports.
We want to Configure VSS on 1 Port of 10Gbase-LX4 and 1 Port of 10Gbase-SR Transceiver.
We thing I want to clarify with Experts:
1: How to break the Current VSS on both Catalyst 6509
2: I know we can run the VSS on 2 Different ports but what about if both Transceiver are different
3: In my case I want to run the VSS on 1 port 10Gbase-SR and 1 Port 10Gbase-LX4 transceiver
Here is Detail about the Line Cards where I want to Run VSS
VS-S720-10G (10Gbase-SR Transceiver)
WS-X6704-10GE (10Gbase-LX4 Transceiver)
Thanks,
JH

That is ok. The physical ports are part of the Porchannel.
So, lets say ports te1/5/4 and 1/5/5 on switch 1 and ports te2/5/4 and 2/5/5 are part of portchannel 10
and now you want to remove 1/5/5 and 2/5/5 from the portchannel.
go under each physical interface and do this command:
no channel-group 10 mode on
this will remove ports 1/5/5 and 2/5/5 from po10 while 1/5/4 and 2/5/4 are not effected.
now you can add whatever new interface from the blade you want to po10 to replace the once you removed.
lets say you want to add interface te1/2/1 and 2/2/1
under the interface add this command
channel-group 10 mode on

X2-10GB-LX4, minimal distance - could I use singlemode patchcord?

I need to connect two 6506 with X2-10GB-LX4, they reside in adjacent racks, so the patch cord length is no more than 10 meters. The X2-10GB-LX4 documentation is not clear about SMF ranges, it only notes that
"Another alternative for short reaches within the same location is to use a single-mode patch cable. There will be no saturation over single-mode fiber. Please note the 10GBASE-LX4 devices can reach up to 10km over single-mode fiber as per compliance to IEEE.".
The MMF notes are much clearer, they say I can use OM2 MMF with mode conditioning patchcords and 5db 1300nm attentuators, also I could use OM3 MMF with same attentuators, but that's the configurations I'd prefer to avoid.
So could I just get an SMF patchcord and plug in to both tranceivers? Have I need to use attentuators or whatever else on such kind of link?

According to the documentation and the specifications, if you use SMF patch cables, you can plug the two LX4 transceivers together without any attenuators or mode conditioning patchcords. The maximum transmit power specification (-0.5dBm) of the LX4 transceiver is equal to the its maximum receiver input specification (-0.5dBm).
The use of the LX4 transceiver for this short distance application is a very costly solution. The SX over MMF would be more economical.
