DESCRIPTION
NEC’s NX7462LE -CC is a 1480 nm pumping laser diode
module with optical isolator for an EDFA (Er Doped optical
Fiber Amplifier) that can expand the transmission span
and compensate optical losses. This device is a Multiple
Quantum Well (MQW) structured Fabry-Perpt (FP) Laser
Diode that features high output power, high efficiency and
stable fundamental mode.
