Optics and Optical Networking

Hello,We have a situation with an optical link where an 2950 and 3550 is able to communicate when they are about 3-5m apart from each other but when they are 1km apart from each other we see lots of input errors. The same 1km link works in between 2x...

Hi,We are doing research at single mode fiber to the locations (Dark Fiber). We want to use Cisco technology to link the locations together. What type of Cisco hardware do I need? HQ <--------> Location 1 <---------> Location 2 <-------> Location 3 <...

Recently we just switch from CES over an ATM backbone to SONET (454s and 327s). We have a requirement for point-to-point T1 circuits. The circuits worked fine over CES and all we did was move the circuits to the SONET. The tail end of the circuit rem...

I have a slight problem that I need some help on. We just ordered a GIG E connection from our bldg to our Co-Lo facility. The problem we are having is that when it was ordered by the engineer in charge of the project he thought that he could termin...

Dear Great's Out there..Hope you all are doing fine and enjoying.I am thinking to go for Gigabit Ethernet for my LAN but not able to start the desing part.Some say GBIC module on Cisco has some distance restriction and I am getting confused.So, let's...

Simple question, can you switch just one port of the DS1-14, to the protect, or do you have to switch all the circits on the card to protect. Is the protection at the card level, or the port level ? Thanks, ...

HiWe are deploying ONS15454 and ONS15310 Release 5 for a customer project. The network is to be managed through CTM corba gateway by a custom built NMS.Although we have most documentation on the customized TMF814 Corba interface, we can't seem to fi...

How can I see the companding paramenters in a VISM card running the 3.1 version?

Many of my LX fiber connections have been going down recently. When I test the gbic with a light meter I get around -30 to -40 dbm, which is really low. I then replaced them with spares and the link comes back up every time. The new gbic's light le...

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
