Optical Cross-Connect Module
An optical cross-connect (OXC) is a device used by telecommunications carriers to switch high-speed optical signals in a fiber optic network, such as an optical mesh network. In the 1980s, when transmission speeds supported by optical fibers increased from 45 Mbit/s to 2. Compared with traditional ROADM based on separate boards and inter-board fiber patch cords, OXC uses integrated interconnections to build an all-optical switching resource pool, achieving highly integrated, fiber. An OXC is a network element that performs optical switching of signals—typically WDM or DWDM channels—routing them from any input port to any output port while remaining in the optical domain.

What is the module called that converts a network port to an optical port
An SFP (Small Form‑factor Pluggable) transceiver is a compact, hot‑swappable module that fits into a switch, router, or media converter. It converts electrical signals into optical (or copper) signals and vice versa. This lets you send data far away. An ONT device is critical in a fiber-to-the-premises (FTTP). These small, hot-pluggable modules are the bridge between electrical signals inside your networking equipment and the light pulses that race through fiber optic cables at near light speed. Learn all about ONTs, how they work, and why they're a critical link in the “last mile” of fibre networks.
