Infineon Technologies has presented a new family of optical components for two-way communication over a single fibre. The costs of bi-directional optical components have dropped to a level where the assembly cost for the PCB becomes a major share of the total cost of ownership. The company's T-BIDI eliminates the need for pin bending, eliminates fibre handling during PCB assembly, and allows an automatic wave soldering process, thus significantly reducing assembly costs.
The bi-directional T-BIDI module consists of a laser and a pin diode with optional pre-amplifier. The emitter and receiver of the T-BIDI are placed in hermetically sealed TO cans and are located at the same side of the module. This makes the module easy to mount anywhere on a PCB, either at the edge or in the middle. Different laser types are available as well as received models with integrated low-noise pre-amplifier. The standard version of the T-BIDI features an MU or LC receptacle.
