Optics and Optical Networking

When looking at the monitor jack of a 15216 OADM with an optical spectrum analyzer, I am seeing for lack of a better term, negatives spikes (like a relection) there are two of them. These are between the first wavelength, and the second wavelenght. T...

Has anyone ever connected two organization's 15454s together with either a subtend ring or PTP and NOT allowed one another access to each others CTC? We want to use our respective systems to transport another parties traffic, but despite organization...

I have single mode fiber connected between a 3560 and the 4506.I am using the ZX (long distance - big bucks) modules.I installed a -10db attenuator between the two pieces of equipment My issue When I do a no shut on the port, the green light comes on...

As title: I have been asked by customer. And I did a show interface wave1/0 <--OSC card. and the outpurt is as below:Wave1/0 is up, line protocol is up Patched Interface(s) : Oscfilter0/0 Channel: 0 Frequency: 191.9 Thz Wavelength: 1562.23 nm...

SONET circuit prices are a deal that we can't refuse. Looking to replace ATM-oc3/CES modules in the 7206VXR with the PA-POS-OC3SMI and t1 cards. Has anyone done this before? Order a noncatenated STM1 for 3 voice t1's and the rest IP data? Thanks

HelloI have a BLSR that is currently using mostly OC48 ELR 1557.36 cards. I am currently only using point to point fiber links, but may be adding DWDM in some parts. I am trying to find out if my cards are 100 or 200 Ghz spacing models. All of the...

Hello Sir,try to use DWDM to extend IP network.is it possible using Catalyst 6500 DWDM GBIC to connect to Lucent Wavestar OLS 400G DWDM ?have any limitation or document for this event ?Please kindly help to suggest.thank you.Jason

I have the -ER XENPAK's already. My maximum distance to run is only 45 meters. will I have problems using the long range XENPAK's(up to 40km) over such a short distance?

We will be changing the DCC on our 15454, 17 node, UPSR, OC-48 ring from SDCC to LDCC. Has anyone done this on a network that is turned up and can this cause any problems? Obviously we will lose communications with the nodes as we change them, but ...

Srp's CPU usage reach to 99% when I inserted a other pos card to GSR. The current IOS version 12.0(26)S.Now is there any method can decrease the cpu usage except upgrading the ios.

We have a situation where there is a Single Mode Dark Fiber used with CWDM solution across 1.5Km. We are now trying to connect Cisco 2950 switches with MMF GBIC (WS-5484) to the CWDM Box over a short distance (5 to 20 mts). The Link is not coming up....

The 15540 has two CPU in order to have a redundancy in case one fails.We would like to know if there is a way to configure the Primary/Secondary, e.g. having the Primary CPU alwyas in Slot 6 and the Secondary in Slot 7, after a Power On Reset.If the...

We have found some errors in the wave2/0,which is a intf. of 15530, but there is no errors in it's transparent2/0/0 interface. What kinda error may occur in the wave interface only?

If I'm running two aps groups on a 76xx. Say aps group 30 on one set of interfaces and aps group 20 on the other. Can I use 'aps working 1' and 'aps protect 1 x.x.x.x' with both groups or does the circuit number need to be different. It shows that it...
