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
