Multichannel bidirectional optical transceiver

Abstract

A multichannel bidirectional optical transceiver is disclosed. The transceiver includes an optical fiber transmitting downstream optical signals and receiving upstream optical signals, a plurality of vertical surface light-emitting sources that generate the downstream optical signals and a plurality of vertical surface light-receiving detectors that receive the upstream optical signals. The transceiver also includes an optical coupler that outputs the downstream optical signals and the upstream optical signals received through the optical fiber to the optical fiber and the vertical surface light-receiving detectors, respectively.
