LASER DIODE
NDL7408P Series
1 310 nm InGaAsP STRAINED MQW DC-PBH LASER DIODE COAXIAL MODULE WITH SINGLE MODE FIBER
DESCRIPTION
NDL7408P Series is a 1 310 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.
FEATURES
• Center wavelength λC = 1 310 nm
•Two types of output power : 1.0 mW (NDL7408PK Series)
0.2mW (NDL7408PL Series)
• |
Low threshold current |
lth = 12 mA TYP. @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
