LASER DIODE
NDL7620P Series
1 310 nm OPTICAL FIBER COMMUNICATIONS
InGaAsP STRAINED MQW-DFB LASER DIODE
COAXIAL MODULE FOR 2.5 Gb/s
DESCRIPTION
The NDL7620P Series is a 1 310 nm λ/4-phase-shifted DFB (Distributed Feed-Back) laser diode coaxial module
with internal optical isolator. Newly developed strained Multiple Quantum Well (st-MQW) structure is adopted to
achieve stable dynamic single longitudinal mode operation over wide temperature range of 0 to +70 °C. It is
designed for STM-16 applications.
FEATURES
• High-speed response
• Peak emission wavelength
• Wide operating temperature range
• Internal optical isolator
• λ/4-phase-shifted DFB
• InGaAs monitor PIN-PD
