Product Profile

OEO6500-2.5G service card is a fiber link wavelength converter. (Signal amplifier). It makes the fiber single’s amplification and wavelength transfer come true) with the theory of lighting-electricity-lighting transfer. We can realize wave division multiple transmissions combined with C/DWDM multiple/multiplexer, which especially suitable for 125M/155M/622M/1.25G/2.5G/S SDH/SONET, Ethernet fiber communication system, which could provide fast and low cost transfer solutions for the transfer line of fiber relay and fiber resources shortage.

Product characteristics:

1. Fiber port’s rate maximize 2.5Gb/s

2. Transmitter wavelength located in C-Band, in the limitation of DWDM wavelength ruled by ITU-T

3. Individually used by management and control

4. Providing self-loopback test

5. Providing 3R function to define the data how to transfer within neighboring ports

6. Providing CDR function to optimize the output of fiber frequency
