A method and apparatus is provided for connecting an optical source to a multimode optical fibre in a multimode optical fibre communications system. A single mode fibre length is provided such that optical radiation admitted from an optical source at one end of the single mode fibre length is provided to a multimode optical fibre at the other end of the single mode fibre length. This method and apparatus is used in a duplex patchcord for connecting an optical transceiver to a pair of installed multimode fibres. The second fibre in the patchcord is a multimode fibre for passing optical signals to the optical receiver of the transceiver.

Multimode communications systems

A micro-photonics device is described that includes a substrate and a plurality of optical and electrical components mounted on the substrate. The optical and electrical components form a transmitter and a receiver. A wall is mounted on the substrate to physically separate some of the components from other components to prevent electrical and optical interference between the transmitter and receiver. The wall mounted on the substrate may also be mounted with electrical and optical components of the micro-photonics device. In this case, the wall physically separates the components mounted on the substrate from the components mounted on the wall to prevent electrical and optical interference. Moreover, the wall with the mounted components may simply be attached to a side surface of the substrate.

An optical connector is provided for connecting an optical fiber to, for example, a laser. The optical connector comprises a housing defining a passage therethrough and a stop for abutment against a face of a ferrule containing an optical fiber. The stop is positioned and shaped so that in use the area of contact between the stop and the ferrule end face is less than 10% of the total area of the end face of the ferrule, and the area of contact between the stop and the ferrule end face is close to a central axis of the ferrule. Many different designs of angled ferrule are available for reducing the level of optical reflections within optical systems. The present optical connector allows these many different designs of angled ferrules to be accurately aligned to an optical device.

Light transmitting device utilizing indirect reflection

An optical transmitter assembly (1) comprises an optical source (20) and an optical detector (20) arranged to receive light output from the source (10) indirectly via a reflector (30). The source (10), the detector (20), and the reflector (30) are mounted on a common support structure (40). A unitized light reflector assembly (70) having the reflector (30) and detector (20) on a ceramic plate (72) is also disclosed.
