LevelOne BIDI Fast Ethernet Media Converter Set RJ45 to SC Single-Fiber, Single-Mode, 20 km, 1310/1550 nm, 2 Units

The LevelOne FVT-2202 is a matched pair of Fast Ethernet media converters that links two 10/100Base-TX copper networks over a single strand of single-mode fibre, up to 20 km apart. Bi-directional (BIDI) optics send and receive on different wavelengths — 1310 nm and 1550 nm — so the link needs one fibre instead of the usual two. It is ideal where fibre is scarce or leased per strand, or where an existing pair needs to carry two separate links.

Both ends come in the box, already matched, each with its own power adapter. Connect each unit's RJ45 port to a switch or device and the SC port to the fibre; Link Fault Pass-through (LFP) signals a broken link to both copper ends, and DIP switches allow manual speed and duplex settings where needed. The units are unmanaged and run at 100 Mbps.

• 2 × LevelOne FVT-2202 media converters (matched BIDI pair)
• 2 × power adapters
• 1 × Quick Installation Guide
• Fibre patch cords are not included

• You get both ends of the link in one order — install one unit at each site and connect them with one single-mode fibre.
• Using one strand per link halves the fibre you need, or lets a spare strand carry a second link.
• Do not mix up the units with other BIDI pairs: each side must face its opposite wavelength.
• 100 Mbps covers CCTV, access control, building management, VoIP and small-site uplinks.
• LFP makes a fibre break visible to the switches at both ends so failover or alarms can react.

• It will not work with standard dual-fibre converters or switch SFPs that use two fibres.
• It will not work over multi-mode fibre.
• It will not run at Gigabit speed.
• It has no web/SNMP management, VLAN or OAM features.
• It does not supply PoE.
