  A forward-path receiver and a burst return-path transmitter are integrated into one compact module. This is a solution
  for migration from HFC to FTTx application for MSOs.

  The downstream signal at 1550nm is detected through an optical WDM filter, and then received by TV set, cable
  modem (CM) or set (STB). Once the return-path signal from CM or STB is detected in this module, the upstream laser is
  turned on and this burst-mode mechanism can reduce ingress noise so that the lower return path band can be used to
  support more services from cable modem.
