Abstract
An optical transceiver performing the full-duplex transmission in a plural channel is disclosed. The optical transceiver provides an optical receptacle, a semiconductor optical device, an inner fiber that optically couples the optical receptacle with the semiconductor optical device, and a fiber tray that secures an extra length of the inner fiber. The fiber tray provides an inner wall inclined toward a direction perpendicular to a direction along which the inner fiber warps. The inner fiber is set within the space as touching the inclined inner wall and sliding thereon toward the inclined direction.
Claims10
An optical transceiver that performs a full-duplex communication between transmitting channels and receiving channels, the optical transceiver comprising:
- an optical receptacle the receives an external optical connector;
- a multiple-fiber push on (MPO) connector that optically couples with the external optical connector, the MPO connector being secured within the optical receptacle;
- a transducer including a laser diode (LD) chip that provides LD elements, and a photodiode (PD) chip that provides PD elements;
- a fiber bundle that includes inner fibers, the inner fibers optically coupling the MPO connector with the LD chip and the PD chip, the fiber bundle having an extra length longer than a distance between the optical receptacle and the transducer;
- a fiber tray that secures the fiber bundle therein;
- and
- a circuit board having primary surface, the circuit board mounting the LD chip, the PD chip and the fiber tray on the primary surface thereof,
- wherein the fiber tray is mounted on the circuit board between the transducer and the optical receptacle, and
- wherein the fiber bundle is warped along a direction connecting the transducer and the optical receptacle in the fiber tray.
An optical transceiver, comprising:
- an optical receptacle that receives an external optical connector;
- a semiconductor optical device optically coupled with the external optical connector through the optical receptacle;
- an inner fiber that optically connects the optical receptacle with the semiconductor optical device, the inner fiber having an extra portion warped along a direction the inner fiber extends;
- and
- a fiber tray having a space that secures the extra length of the inner fiber therein,
- wherein the space of the fiber tray provides an inner surface inclined toward a direction perpendicular to the direction along which the inner fiber warps.
