Remote PHY and Fiber Deep

A key transformation towards next-generation gigabit networks. CATV and multiple-system operators (MSOs) are transforming their networks to support DOCSIS 3.1 and eventually FTTH/EPON. Fiber deep is a key part of how next-gen cabling is being deployed—as it pushes fiber ever closer to subscribers for a better customer experience. Gear up for the transition to next-gen technologies.


The current architecture of fiber deep with node plus zero architecture (Node+0) is migrating Remote PHY (RPHY) which will require a significant increase in number of nodes and new fibers to connect them. This transformation also requires a major upgrade of the core/backbone networks to support 100G+, important changes in the head-ends to turn them into mini-data centers which will feed the multiple nodes with DWDM Ethernet signals. This new network infrastructure potentially represents an important shared fronthaul for 5G antennas, enabling new services for the carriers.
