DESCRIPTION
The NDL7701P Series is a 1550 nm
λ/4-phase-shifted
DFB
(Distributed Feed-Back) laser diode with single mode fiber.
The newly developed strained Multiple Quantum Well (st-
MQW) structure is adopted to achieve stable dynamic single
longitudinal mode operation over a wide temperature range of
-20 to +85°C. It is designed for all STM-1 and STM-4 applica-
tions.
