Claim 0:
1. A device configured for communication in a passive optical network that includes at least one optical line terminal (OLT) and at least one optical network unit (ONU), the device including at least one of a wavelength division multiplexer and a wavelength division demultiplexer, and a plurality of fiber link modules (FLM), each FLM comprising:
an upstream multiplex conversion device (MCD) connected to a respective port of each at least one of a wavelength division multiplexer and a wavelength division demultiplexer, the upstream MCD comprising:
an upstream optical receiver that receives an upstream optical signal from said at least one ONU; and
an upstream optical transmitter having a laser that transmits a regenerated upstream optical signal to said at least one OLT, wherein
the upstream optical receiver is a burst-mode receiver electrically coupled to the upstream optical transmitter, and
the upstream optical receiver and the upstream optical transmitter are configured to provide an enable/disable signal for the laser from the upstream optical receiver to the upstream optical transmitter; and

a downstream MCD connected to the respective port of each at least one of a wavelength division multiplexer and a wavelength division demultiplexer, the downstream MCD comprising:
a downstream optical receiver that receives a downstream optical signal from said at least one OLT, wherein the downstream optical signal is a wavelength division multiplexing (WDM) signal;
a downstream optical transmitter that transmits a regenerated downstream optical signal to said at least one ONU; where

the upstream MCD and downstream MCD of each FLM is connected to a respective port of each at least one of a wavelength division multiplexer and a wavelength division demultiplexer that is different than that of other ones of the plurality of FLMs.
