Product Identity

The PLANET FT-806A20 is a 10/100Base-TX to 100Base-FX media converter that uses single-mode WDM technology over a single SC fibre strand. It transmits at 1310 nm and receives at 1550 nm for distances up to 20 km, making it suitable for FTTH, FTTC and FTTB deployments where long-reach fibre links are required. The unit operates on a 5 V DC supply provided by an included 100-240 V AC adapter.

Suitable Installations

Network engineers extending copper Ethernet segments over single-mode fibre with WDM will find this converter matches the 10/100 speed profile and 20 km reach needed for campus or last-mile links. It supports both half-duplex and full-duplex modes with automatic adaptation on the TP port. Buyers needing multi-mode fibre, dual-strand connectors or gigabit throughput must select a different converter.

Deciding Specification

The single-strand SC WDM interface fixed at 1310 nm TX and 1550 nm RX determines whether this unit fits the existing fibre plant; the link will not operate if the remote end uses reversed wavelengths or a different connector type.

Highlights

  • Extends network reach up to 20 km over single-mode fiber
  • Bi-directional WDM uses 1310 nm TX and 1550 nm RX wavelengths
  • Auto-negotiates 10/100 Mbps for full or half-duplex operation
  • Compact 1.02 x 3.82 x 2.72 in design fits tight spaces
  • Wide 0 to 50 °C operating range suits varied environments

Questions about this item

What IEEE 802.3 standard does the FT-806A20 converter support and what practical speed does it cap at?

The converter follows IEEE 802.3, 802.3u 100BASE-TX and 100BASE-FX, delivering 10/100 Mbps twisted-pair to 100 Mbps fibre with full-duplex operation reaching 200 Mbps effective throughput.

What physical space and mounting provisions does the FT-806A20 need?

The unit measures 1.02" high, 3.82" wide, 2.72" deep and weighs 0.44 lb; it is a desktop converter with no rack ears or DIN clips, so it simply sits on a flat surface near a power outlet.

How is the FT-806A20 installed and which step is often missed?

Connect the SC single-mode fibre (TX 1310 nm, RX 1550 nm), plug the RJ-45 copper link, then attach the 5 V DC 2 A adapter to the 100-240 V AC supply; the step often missed is confirming the fibre link light shows full duplex before assuming the 20 km path is live.
