タイトルまたは説明

Fiber media converters are simple networking devices that make it possible to connect two dissimilar media types such as twisted pair with fiber optic cabling. They were introduced to the industry nearly two decades ago, and are important in interconnecting fiber optic cabling-based systems with existing copper-based, structured cabling systems. They are also used in MAN access and data transport services to enterprise customers.

Fiber media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fiber optics.

Media converter types range from small standalone devices and PC card converters to high port-density chassis systems that offer many advanced features for network management. Simple Network Management Protocol (SNMP) enables proactive management of link status, monitoring chassis environmental statistics and sending traps to network managers in the event of a fiber break or even link loss on the copper port.

Fiber media converters can connect different LAN media, modifying duplex and speed settings. Switching media converters can connect legacy *0BASE-T network segments to more recent **0BASE-TX or **0BASE-FX Fast Ethernet infrastructure. For example, existing Half-Duplex hubs can be connected to **0BASE-TX Fast Ethernet network segments over **0BASE-FX fiber.
