cwdm mqw-dfb laser diode module
description
dld-c48x series are ingaasp/inp mqw-dfb laser diode modules，designed for fiber optic communication systems. these modules are ideally suitable for long reach and intermediate reach of 622mb/s and 2.5gb/s transmission applications. a laser diode is mounted into a coaxial package integrated with an ingaas monitor pd. especially dld-c48x series have a single-stage optical isolator integrated inside.
features

● data rate up to 2.5gbps
● low threshold current
● designed to meet telcordia (bellcore)
and itu-t requirements
● ngaasp/inp, smqw lasers
● multiple package types available
applications
● sonet oc-48/sdh stm-16
● long-haul transmission systems
