Baudcom, BDTR-303 transceiver is a series single mode single fiber module designed for optical data communication applications. It is electrically 
  compatible with the two fibers MSA transceiver.Integrated with 1310/1550nm WDM coupler to achieve up to 80km point-to-point single fiber application, the transceiver modules support data 
  rates up to 155Mbps.The transceiver module supplies the Differential 
  PECL of 3.3/5.0 Voltage. Together with BDTR-5** series module, they can provide the system designer with products to implement a range of FDDI and 
  ATM designs at the 100Mbps/125Mbps rate and SONET/OC-3、SDH/STM-1 for Telecommunication.The transceiver has excellent reliability. 
  Commercial level transceiver module which operating at 0℃ to 70℃ and Industrial level which operating extended temperature as -40℃ to +85℃ 
  for available.
