This document describes the features and characteristics of MITSUBISHI LASER DIODES ML7xx45 series products. These products are InGaAsP laser diodes that provide a stable, single transverse mode oscillation with an emission wavelength of 1310nm and a standard continuous light output of 5mW. The ML7XX45 series is suitable for applications such as FTTH and 1Gbps Ethernet/Fiber channel systems.
The ML7xx45 series are InGaAsP Fabry‑Perot laser diodes offering a typical 1310 nm emission wavelength, low threshold current and stable single‑mode operation over a wide temperature range. They are hermetically sealed with flat‑window or ball‑lens caps for optical output monitoring, suitable for FTTH and 1 Gbps Ethernet/Fiber Channel applications.
The document provides absolute maximum ratings, electrical/optical characteristics, and mechanical outline drawings for the various part numbers (ML720J45S, ML720K45S, ML720Y45S, ML725B45F, ML725C45F). Key parameters such as threshold current, operating voltage, and temperature limits are listed for design reference.
