US Patent 7418208 Optoelectronic transceiver for a bidirectional optical signal transmission

An optoelectronic transceiver for a bidirectional optical signal transmission including a housing having a width of at most 13.5 mm, a first bidirectional optical subassembly arranged in the housing and serving for the simultaneous emission and reception of optical signals, a second bidirectional optical subassembly arranged in the housing and serving for the simultaneous emission and reception of optical signals, and an optical interface for the coupling of two optical waveguides, it being possible for a respective optical waveguide to be optically coupled to a subassembly. The invention enables a simultaneous bidirectional data transmission on both ports of the transceiver and thus an increase in the transmission capacity of the transceiver.
