Optical-Electrical-Optical Converter

The ENTU 763GO is an Optical-Electrical-Optical (OEO) signal converter, which has two SFP sockets. It can convert two optical digital signals of SFP modules, which maybe different wavelength, different distance or different mode (single mode/multi mode fiber) and same speed at 100M Hz or 1G Hz auto detection. It allows the operator to maintain the ENTU 763GO with IEEE 802.3ah Link Layer OAM and TS-1000 OAM at CO or CPE mode.
