A pluggable optical module for use with optical communication systems, wherein the pluggable optical module comprises a housing having an opening arranged to receive a subassembly, wherein the subassembly is capable of being removably inserted into the housing.

Pluggable optical subassembly

A variable decision threshold apparatus includes a comparator for receiving the electrical signal and for comparing it to a threshold level. A signal strength monitor monitors the strength of the electrical signal and a scaler scales the decision threshold level to the measured amplitude of the electrical signal so that the percentage set as the threshold level is maintained.

Variable decision threshold apparatus

A fibre optic transceiver in which the optical components, interface, management functionality and management interface are all integrated on a single module, capable of being plugged into and removed from the telecommunication's parent system includes a housing having disposed therein a transmitter and a receiver. The housing further includes a pair of rails disposed on opposite sides of the housing to enable the module to be plugged into a suitably configured board. The module is designed primarily for use in 10Gbit serial optical systems, but is equally applicable for use in WDM applications, as well as at other speeds and wavelength.

Fiber optic transceiver module

An optoelectronic component, such as an optical transceiver, contains one or more optoelectronic devices, such as a semiconductor laser or a photodiode. It also contains a metallic or metallized housing within which the optoelectronic devices are mounted, and an optical connector part to allow optical radiation to be coupled between the optoelectronic devices and fibres of a fibre optic communications network. The optical connector is disposed at least partly within an aperture in the housing. A metallic or metallized barrier is disposed between the one or more optoelectronic devices and the optical connector substantially to shield against transmission of electromagnetic radiation through the aperture (except of course for the transmission of optical radiation to be provided to, or received from the fibre optic communications network). This barrier can be provided as part of a metallized clip, adapted to fit around the optical interface between the optoelectronic devices and the outside of the transceiver. The optoelectronic devices may be separated into an optical assembly and an electrical assembly, each with a separate conductive shield, in which case the metallized barrier may provide a part of the conductive shield for the optical components on the optical assembly.
