Patent number: 11689287Abstract: 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.Type: GrantFiled: August 13, 2021Date of Patent: June 27, 2023Assignee: COX COMMUNICATIONS, INC.Inventor: Harjinder S.
