InGaAsP MQW-DFB LASER DIODE COAXIAL MODULE
DESCRIPTION
The NDL7705P Series is a 1 550 nm phase-shifted DFB (Distributed Feed-Back) laser diode module with optical
isolator. Multiple Quantum Well (MQW) structure is adopted to achieve stable dynamic single longitudinal mode
operation over wide temperature range of
40 to +85 C.
It is designed for all STM-1 and STM-4 applications.
FEATURES
• Peak emission wavelength
• Optical output power
• Wide operating temperature range
• /4-phase-shifted DFB
• InGaAs monitor PIN-PD
• Internal optical isolator
