Optical wavelength division multiplexer and/or demultiplexer mounted in a pluggable module

摘要

A low profile optical wavelength division multiplexer and/or demultiplexer is provided which is carried in a pluggable module and adapted for detachable connection to a host device. The device includes a three strata optical subassembly including a substrate, a molded plastic coupling module and an optical block either connected to or integrally formed with the molded coupling module. The device can be used with either horizontally or vertically pluggable modules. The device has one embodiment capable of mounting in a GBIC compliant module.
