1 / 5 page 1310 nm InGaAsP STRAINED MQW DC-PBH LASER DIODE COAXIAL MODULE WITH SINGLE MODE FIBER NDL7408P SERIES FEATURES • CENTER WAVELENGTH λC = 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 = 25 °C • HIGH CUT-OFF FREQUENCY fC = 2.0 GHz • InGaAs MONITOR PIN-PD • WIDE OPERATING TEMPERATURE RANGE: -40 to +85 °C • BASED ON BELLCORE TA-NWT-000983 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.
