Abstract
An optical transceiver with inner fibers to couple optical parts installed therein is disclosed. The optical transceiver of an embodiment includes a tray for arranging the inner fibers. The tray, which may be made of metal plate, includes a primary plane in contact with the electronic parts, the contact plane in contact with the housing, and the turn connecting the planes. The tray has a U-shaped cross section with a space surrounded by both planes, the turn, and the housing, where the inner fibers are secured in the space.
Claims14
An optical transceiver, comprising:
- an optical subassembly;
- an optical component optically coupled with the optical subassembly by an inner fiber;
- an electrical component mounted on a circuit board, the electrical component generating heat;
- a tray for guiding the inner fiber;
- and
- a housing for enclosing the optical subassembly, the optical component, the electrical component and the tray therein,
- wherein the tray comes in contact with the electronic component and the housing to secure a heat dissipating path from the electrical component to the housing.
A pluggable optical transceiver capable of receiving a wavelength multiplexed optical signal and transmitting another wavelength multiplexed optical signal, comprising:
- a housing including a first section and a second section;
- a plurality of receiver optical subassemblies (ROSA) and a plurality of transmitter optical subassemblies (TOSA), the ROSAs and the TOSAs being mounted on the first section of the housing;
- an optical multiplexer and an optical de-multiplexer each mounted on the first section of the housing;
- an electronic circuit electrically coupled with the ROSAs and the TOSAs, the electronic circuit being mounted on the second section of the housing;
- a plurality of inner fibers, a part of which connects the optical de-multiplexer with the ROSAs and another part of which connects the optical multiplexer with the TOSAs, the inner fibers being drawn from the first section and bent;
- and
- a tray for guiding the inner fibers in the second section,
- wherein the tray provides a heat dissipating path from the electronic circuit to the housing.
