Pair of compact metal media converters with SC and RJ45 ports

BFKK

BFKK BiDi Gigabit Single Mode SC Media Converter 20km 1 Pair

SKU CH-WXH9-87KEH

Converts single-mode SC fibre to Gigabit Ethernet over distances up to 20 km using 1310/1550 nm BiDi wavelengths

  • BiDi single-fibre design cuts cabling cost by using one SC strand for 20 km reach
  • Gigabit RJ45 port auto-negotiates 10/100/1000 Mbps with MDI/MDI-X crossover
  • Plug-and-play operation complies with IEEE 802.3 standards and supports 9 K jumbo frames
  • Metal case with dual-side cooling holes dissipates heat for reliable long-term use
  • Built-in lightning protection and strong anti-interference shield the link in harsh environments

BiDi Gigabit Media Converter Pair

This BFKK media converter pair links single-mode fibre to copper Ethernet over distances up to 20 km. Each unit integrates a 1000Base-FX SC port operating at 1310 nm and 1550 nm with a 10/100/1000Base-T RJ45 port. The plug-and-play design requires no software configuration and complies with IEEE 802.3 family standards.

Upgrading Legacy Copper Links

The converters replace direct copper runs that cannot reach remote buildings or campuses. They become worthwhile when the link distance exceeds standard twisted-pair limits or when electromagnetic interference makes copper unreliable. Jumbo frame support up to 9K bytes helps maintain throughput for large data transfers.

Installers Extending Campus Networks

Network technicians deploying fibre backbones between switches, routers or wireless access points will find the metal-housed units suitable for indoor or sheltered outdoor use. Buyers who need multi-mode fibre, dual-strand connectors, or Power over Ethernet on the copper side should look at other products.

Questions about this item

What fibre connector and wavelength pair does this converter use?

It uses a single SC port with a built-in module that transmits at 1310nm and receives at 1550nm for single-mode fibre up to 20km.

Does the converter need any configuration after connecting the SC and RJ45 cables?

No, it is plug-and-play; simply connect the fibre and copper cables and it links automatically with MDI/MDI-X crossover support.

What cooling features does the metal case provide for continuous operation?

The case has cooling holes on two sides for passive heat dissipation, and the internal chip includes lightning protection for durability.
