Transfer GPS Timing Signals over Fiber
(1/2) > >>

Hello, I want to transfer the 1pps and 10Mhz timing signals from a GPS receiver over fiber. Could I convert the single-ended timing signals to differential CML and connect it directly to the Fiber Optic differential receive pins? I'm thinking about using the Cisco CWDM-SFP10G-1470-20 Compatible 10G CWDM SFP+ 1470nm 20km DOM Transceiver Module. At the destination could I recover the timing signals by converting the differential CML to singled-ended?

 

Thanks,

Joe

If you're already using a WDM network perhaps check if your equipment can do sync-e and use that?
joe306:
Will do but I need to design a board to take in the GSP Timing Signals and send that information over fiber and then convert it back.

You really want to use the GPS receiver as close as possible to your equipment. Driving those SFP modules is not trivial.

Sounds interesting!
