FITB-OEO800-2G5 Board Overview
FITB-OEO800-2G5 is an optical fiber link wavelength conve er (fiber amplifier). It regenerates optical signals in the principle of optical-electrical-optical to realize the amplification and wavelength conversion of optical signals. Wavelength division multiplexing can be realized by using C/DWDM multiplexer/de-multiplexer, which especially applies to optical transpo systems such as 125M/155M/622M/1G/2G5/s SDH/SONET, Ethernet etc. It provides rapid and cost-efficient solutions to regeneration of optical signals and transmission of rare fiber resources.
Key Features
It suppo s a maximum po rate of 2.5Gb/s, and is compatible with 125M/155M/622M/1.25G The wavelengths of the transmitter is at C-Band, which suppo s DWDM wavelengths in compliance with ITU-T standards It can be operated and controlled independently It suppo s automatic loopback test It suppo s CDR function, which can optimize outputIt suppo s shut-down when there is no optical signal
