Thank You Bob Evans CTO
Hello, I was looking for feedback on the following question:- When connecting two MM SFP/SFP+/XFP 's together...(short range). What should be the best practice receive power range ? Is it true that if the rx power is higher than (x?) then it shortens the life of the optics ?
Yes, but thats only true about single mode frequencies not multimode (MM) because those are not as powerful. All MM is expected to go a very limited distance, so levels are never high. We have MM 3 foot jumpers between gear running for years.
(assumption being made here is that MAX Rx Power is not being exceed as per the spec sheets of the optics) Regards Faisal Imtiaz Snappy Internet & Telecom 7266 SW 48 Street Miami, FL 33155 Tel: 305 663 5518 x 232 Help-desk: (305)663-5518 Option 2 or Email: Support () Snappytelecom net
