Mitsubishi Electric Corp. has released details regarding its upcoming launch of a 10 Gpbs optical transmitter for high-speed, large-volume data transmission between base stations and central offices in radio access networks.
The optical transmitter module combines an electro-absorption modulator laser (EML) and a transmitter optical sub-assembly (TOSA) in order to reduce fluctuations in optical wavelengths for dense wavelength-division multiplexing (DWDM).
Mitsubishi says in Long Term Evolution (LTE) and 4G mobile systems, DWDM has attracted attention as a way to reduce the power consumption of optical transmitter modules. The EML-TOSA module can operate in temperatures up to 95 degrees Celsius, reduces the size of optical transmission equipment, reduces power consumption of thermoelectric cooler by about 50 percent compared to previous Mitsubishi devices and as it is compatible with DWDM, contributes to increased traffic capacity, Mitsubishi says.
The module is slated to be launched commercially on Feb. 1.
