Embodiment Construction

[0022] An optical fiber is a cylindrical dielectric waveguide that sends light along its axis. The optical fiber consists of a transparent core surrounded by a transparent cladding (hereinafter "cladding"), both of which are made of a dielectric material. Light is kept in the core by the phenomenon of total internal reflection. To confine the optical signal in the core, the core has a higher index of refraction than the cladding. The boundary between the core and cladding can be abrupt (as in step-index fibers) or graded (as in graded-index fibers). Optical fibers can be made of glass or plastic.

[0023] Optical networking using plastic optical fibers (POF) outperforms copper wires in terms of weight, size, bandwidth, power, and electromagnetic immunity. POF has advantages over glass optical fiber (GOF) in terms of ease of handling, installation and maintenance. POF core materials can range from acrylate to perfluorinated polymer. POF exponential distributions can range ...

Abstract

The invention discloses a single-wavelength bidirectional transceiver with an integrated optical fiber coupler. An apparatus configured to function as a pluggable single-wavelength bidirectional transceiver in a switching network. The apparatus includes a 2*1 fusion coupler; an input / output optical fiber, a detector optical subassembly (OSA) fiber and a laser OSA fiber all connected to the 2*1 fusion coupler; and a transceiver that includes a transceiver electronic circuit printed wiring board (PWB) and laser and detector OSAs electrically coupled to the transceiver electronic circuit PWB. Thelaser OSA includes a laser that is situated to transmit light to the laser OSA fiber, while the detector OSA includes a photodetector that is situated to receive light from the detector OSA fiber. The transceiver electronic circuit PWB also includes a multiplicity of transceiver input / output metal contacts arranged at one pluggable end of the PWB.

Description

Background technique [0001] The technology disclosed herein generally relates to fiber optic networks that enable communication between electrical components. [0002] Fiber optic bi-directional transceivers have been successfully deployed in avionics networks to replace copper cables for size, weight and power reduction. In addition, large-scale high-speed (eg, greater than 1 gigabit / second or Gbps) switching networks have been proposed for next-generation aircraft using a large number of single-fiber bi-directional optical links in the aircraft. [0003] Existing bi-directional transceivers used in some avionics networks require two wavelengths to operate. Constantly tracking which bidirectional transceivers have the correct matched wavelength pair in each fiber optic link places a burden on designers and installers of large switched network systems. For some large-scale switched networks designed for use in avionics systems, the constant tracking of matching wavelength pa...
