DESCRIPTION

The NX7460LE is a 1 480 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. It has a strained Multiple

Quantum Well (st-MQW) DC-PBH laser diode that features high output power, high efficiency, and stable

fundamental mode.

FEATURES

• InGaAsP strained MQW DC-PBH laser diode

• High output power

• Internal optical isolator, thermoelectric cooler and InGaAs monitor photo diode

• Hermetically sealed 14-pin butterfly package

• Single mode fiber pigtail

• Wide operating temperature range
