Technological Evolution of Optical Cross-Connect (OXC)
OXC (optical cross-connect) is an evolved version of ROADM (Reconfigurable Optical Add-Drop Multiplexer). As the core switching element of optical networks, the scalability and cost-effectiveness of optical cross-connects (OXCs) not only determine the flexibility of network topologies but also directly impact the construction and operation and maintenance costs of large-scale optical networks. ...Read more -
PON is really not a “broken” network!
Have you ever complained to yourself, "This is a terrible network," when your internet connection is slow? Today, we're going to talk about Passive Optical Network (PON). It's not the "bad" network you think of, but the superhero family of the network world: PON. 1. PON, the "Superhero" of the Network World PON refers to a fiber optic network that uses a point-to-multi...Read more -
