  • Patent number: 11689287
    Abstract: This disclosure describes, among other things, an Optical Communications Module Link Extender (OCML) including embedded Ethernet and PON amplification rather than relying on a separate amplification module for Ethernet and/or PON signals transmitted through the OCML. Providing an OCML that is able to provide the appropriate amplification to transmit both Ethernet and PON signals may be accomplished by using one or more Raman pumps on the signals transmitted in the upstream direction through the OCML (for example, upstream from one or more customer devices to one or more OLTs for PON signals. This OCML configuration may allow for a more cost-effective and efficient system with a smaller footprint than a system that relies on external amplification modules to transmit Ethernet or PON signals.

  • Patent number: 11616591
    Abstract: This disclosure describes C and L band optical communications module link extender, and related systems and methods. An example method may include receiving, by a dense wave division multiplexer (DWDM) at a headend, one or more optical data signals over a C band and an L band. The example method may also include combining the one or more optical data signals. The example method may also include outputting a second signal to a first WDM at the headend. The example method may also include separating, by the first WDM, the second signal into a C band signal and an L band signal. The example method may also include outputting the C band signal to a first amplifier at the headend and the L band signal to a second amplifier at the headend. The example method may also include amplifying, by the first amplifier, the C band signal. The example method may also include outputting an amplified C band signal to a coexistence filter.
