I have a pair of old 10/100 fibre converters on either end of a fibre optic run. The collision light is on permanently on both of them and network performance over the link is abysmal. I think one of them malfunctioned because of a power surge (maintenance had to reset some trip switches this morning and the problem began) . Can I replace one of them or do I need to change both, bearing in mind the new one will probably be a gigabit converter or better? Their is no brand name on the converters. The collision light stays on even if no cables are plugged into the converter ( I presume you cannot have collisions if their are no cables plugged in).

Fibre converters - do I need to match them

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
