Abstract: A multi-channel optical transceiver includes a multi-channel transmitter optical subassembly (TOSA), a multi-channel receiver optical subassembly (ROSA), and a dual fiber type direct link adapter directly linked to the TOSA and the ROSA with optical fibers. The adapter is also configured to receive pluggable optical connectors, such as LC connectors, mounted at the end of fiber-optic cables. This dual fiber type direct link adapter thus provides the optical input and output for the transceiver, which may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a dual fiber type direct link LC adapter. It consists of an adapter body that has two distinct areas: one end for plugging in LC connectors (pluggable connector end) and another end with two slots (direct link end). The adapter also includes two direct link connector assemblies, which fit into these slots. Each assembly has an LC connector receptacle designed to receive a part of an LC connector for optical connection, and is also designed to be mechanically attached to an optical fiber at its other end. An adapter cover is also included to secure these direct link connector assemblies within their slots.
