Abstract
Exemplary embodiments of the invention relate to an optical transceiver module having a status indicator assembly, wherein the status indicator assembly is configured to visually display the operational status of the transceiver transmitter and receiver components. The operational status is accessible while the transceiver operates in conjunction with an external host and may be ascertained in real time without interrupting normal transceiver operation or suspending the transmission of data over optical fibers.
Claims19
A transceiver module comprising:
- a housing;
- a printed circuit board at least partially enclosed in the housing;
- a transmitter optical subassembly enclosed in the housing and communicatively coupled to the printed circuit board for transmitting high-speed data;
- a receiver optical subassembly enclosed in the housing and communicatively coupled to the printed circuit board for receiving high-speed data;
- a controller enclosed in the housing that monitors the transmission and reception of the high-speed data over the transmitter optical subassembly and the receiver optical subassembly, wherein the controller collects status describing the transmission and reception of the high speed data and wherein the controller is configured to communicate transmission information to a user via at least one status indicator;
- and
- a status indicator assembly enclosed in the housing and communicatively coupled to the controller, wherein the controller conveys the status over the status indicator assembly such that the status is visible from outside the housing and capable of being understood by a human eye, and wherein the status indicator assembly includes an aperture configured to interface with the status indicator assembly, and wherein the aperture having formed ends in the shape of an arrow representing the existence and direction of data transmission.
A transceiver module comprising:
- a housing having a status indicator window mounted on a face of a transceiver;
- a transmitter optical subassembly enclosed in the housing and communicatively coupled to a controller for transmitting high-speed data;
- a receiver optical subassembly enclosed in the housing and communicatively coupled to the controller for receiving high-speed data;
- a status indicator assembly enclosed in the housing and communicatively coupled to the controller, wherein the status indicator assembly comprises at least one light-emitting diode configured to represent an operational status of a transceiver component, wherein the operational status is visually conveyed through the status indicator window, and wherein the at least one light-emitting diode communicates the operational status of the transceiver including at least two of a TxDisable, a TxFault, and a RxLOS.
The transceiver module of 12, wherein the at least one light emitting diode is mounted to the printed circuit board such that each light-emitting diode can be separately controlled.
