Fiber media converter

They are also used in metropolitan area network (MAN) access and data transport services to enterprise customers.

As premises networks are primarily copper-based, media converters can extend the reach of the LAN over single-mode fiber up to 160 kilometers with 1550 nm optics.

[citation needed] Wavelength-division multiplexing (WDM) technology in the LAN is especially beneficial in situations where fiber is in limited supply or expensive to provision.

[citation needed] Other benefits of media conversion include providing a gradual migration path from copper to fiber.

Switching converters contain a network bridge and can connect two half-duplex segments without joining their collision domains.
