Optics and Optical Networking

Hi,I've searched intensively but I haven't figured out how far can reach a 15540 with 2x10G wavelenght using 15501 for amplification ?It's possible to reach 600Km using 8-10 15501 ?Can somebody point me to a link.Also maybe I'm wrong but I've read t...

In ONS 15540 training module 2, titled "Backplane and Chassis Configuration" page 5 provides a detailed breakdown of the fixed and non-configurable MUX/DMUX linecard to Transponder linecard backplane cross connects (wrt 4 & 8 Channel OADM's).The text...

Hi My question is regarding a latency on one of our OC48 transatlantic circuit from new york to london. This circuit has provisioned by a US based carrier. We used to have a 80ms of ping replies and now it has jumped to 110ms. I investigated and cou...

If we accidentally put the too strong signal(more than -8 dBm for ONS15540). Could it damage both optical mux/demux and the transponders? On my understanding, since the optical mux/demux is passive optical component then it should be able to stand th...

Ive noticed something odd about VT Tunnels. There does not seem to be an easy way to view what VTs are contained in a given tunnel. The details on the Tunnel just shows the path and the STS used but not whats inside it. Also, when deleting a tunne...

I am using GBICs in 3550s. Two in each switch. GBICs feed the OADMs. All switches/OADMs are in a ring topology (real ring, not collapsed). Is it right to say that the solution is fault-tolerant. One two nodes going down doesn't take any other node do...
