NDL7401P Series
1 310 nm InGaAsP STRAINED MQW DC-PBH LASER DIODE
COAXIAL MODULE WITH SINGLE MODE FIBER
DESCRIPTION
NDL7401P Series is 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 and
access network systems.
The series is also available in FC-PC and SC-PC connector.
FEATURES
• Center wavelength
• High output power from fiber
• Low threshold current
• High cut-off frequency
• InGaAs monitor PIN-PD
• Wide operating temperature range
• Based on Bellcore TA-NWT-000983
