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.
