LASER DIODE
NX7460LE
1 480 nm EDFA APPLICATION InGaAsP STRAINED MQW DC-PBH LASER DIODE MODULE
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 Pf = 120 mW MIN. @ IF = 550 mA CW · Internal optical isolator, thermoelectric cooler and InGaAs monitor photo diode · Hermetically sealed 14-pin butterfly package · Single mode fiber pigtail · Wide operating temperature range TC = 0 to +65 °C
