Modern sub cables does not used a distributed line of EDFAs anymore. They use the entire cable length as an amplifier instead. If the laser is down, you can reach it and service it, since it sits on dry land anyways. I have an EDFA lying around my office desk. Never know when I need one. Uses a 250 mW 850 nm pumping laser.
