| 1310 nm InGaAsP STRAINED MQW DC-PBH LASER DIODE COAXIAL MODULE WITH SINGLE MODE FIBER FEATURES * CENTER WAVELENGTH C = 1310 nm * TWO TYPES OF OUTPUT POWER: 1.0 mW (NDL7408PK Series) 0.2 mW (NDL7408PL Series) * LOW THRESHOLD CURRENT: ITH = 12 mA TYP at TC = 25C * HIGH CUT-OFF FREQUENCY fC = 2.0 GHz * InGaAs MONITOR PIN-PD * WIDE OPERATING TEMPERATURE RANGE: -40 to +85C * BASED ON BELLCORE TA-NWT-000983 NDL7408P SERIES DESCRIPTION The NDL7408P Series is a 1310 nm laser diode coaxial module with single mode fiber. It has a strained Multiple Quantum Well (st-MQW) structure and a built-in InGaAs monitor photo diode. It is recommended for junction or access network systems. The series is available in two types of output power: 1.0 mW and 0.2 mW.
