Light transmitting/receiving module

摘要

Simultaneous bidirectional transmission type LD/PD module having a substrate, a signal transmitting part mounted on the substrate, a signal receiving part formed on the substrate, an end of a fiber communicating with a base station, a light waveguide coupling the fiber to the transmitting part and the receiving part, a filter separating the receiving signal light from the transmitting signal light and a resin mold package containing the substrate, the transmitting part, the receiving part, the filter and the lead frame. The receiving part is electromagnetically shielded with multihole metal members from the noise generated by the transmitting part. The resin penetrates through the holes and fully covers the receiving part.
