Abstract

An optical transceiver includes: an optical reception circuit which converts a first optical signal received from an optical cable into a first electrical data signal and outputs the first electrical data signal; an optical transmission circuit which converts a second electrical data signal into a second optical signal and outputs the second optical signal to the optical cable; a noise detection unit which detects power supply noise from a power supply voltage; and a control unit which sets at least one of operational characteristics of the optical reception circuit and operational characteristics of the optical transmission circuit in accordance with a detection result of the noise detection unit.

Description

technical field [0001] The present invention relates to optical transceivers and methods of controlling these optical transceivers, each of which is connected to an optical communication device and an optical fiber cable, and is implemented by converting an electrical signal into an optical signal and converting an optical signal into an electrical signal Sending and receiving of optical signals. [0002] This application is based on and claims priority from Japanese Patent Application No. 2010-116657 filed on May 20, 2010, the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0003] Optical transceivers are optical transmitting and receiving modules each bidirectionally connected between an optical communication device and an optical cable. Optical transceivers implement transmission and reception of optical signals by converting electrical signals into optical signals and vice versa. As FTTH (fiber-to-the-home) services becom...
