Abstract
A bidirectional optical subassembly (BOSA) optical networking unit (ONU) generally includes a BOSA housing. A tunable laser is located in the BOSA housing and is configured to generate a first optical signal for transmission at a first selected wavelength based on temperature control. The tunable laser is a distributed feedback (DFB) laser diode. A thermal management device is also located in the BOSA housing and is configured to provide the temperature control. A photo diode is further located in the BOSA housing and is configured to receive a second optical signal at a second selected wavelength. The BOSA housing comprises an alloy of stainless steel or an alloy of Kovar.
