Two compact white media converters with SC and RJ-45 ports side by side

BFKK

BFKK 2 Pack Gigabit Ethernet Media Converter 1310 nm 20 km SC Single Mode

SKU CH-J7WR-ERT7A

A pair of gigabit media converters extending single-mode fibre links to 20 km with SC connectors and RJ-45 copper ports

  • Extend network up to 20 km over single-mode fibre
  • Gigabit Ethernet over RJ-45 and SC ports
  • Plug-and-play setup with auto-negotiation
  • LED indicators show link, activity and power status
  • Operates reliably from 0 °C to 60 °C

Dual Gigabit Fibre Converters

This pair of BFKK media converters links two RJ-45 copper ports to single-mode SC fibre at 1310 nm, extending a Gigabit or Fast Ethernet segment up to 20 km. Each unit accepts Cat.5e or Cat.6 cable up to 100 m and negotiates 10, 100 or 1000 Mbps automatically with full or half duplex and MDI/MDIX crossover. External power supplies and a manual are included, and the modules operate from 0°C to 60°C with 9 KB jumbo-frame support.

Installers Needing Long Reach

The kit suits installers who must bridge buildings or campuses beyond copper limits without managed-switch features. It does not serve buyers who need more than two endpoints, redundant power inputs, DIN-rail mounting, VLAN tagging or SNMP monitoring. Users requiring multimode fibre, dual-strand connectors or Power-over-Ethernet injection should look at other products.

Single-Mode SC at 1310 nm

The decisive specification is the built-in single-mode transceiver using a single SC connector at 1310 nm for 20 km reach. Compatibility hinges on matching that wavelength and connector type on the far end; the link will not operate with multimode cable, dual-fibre patch cords or a different wavelength module. Compliance with IEEE 802.3, 802.3u and 802.3af ensures baseline interoperability with standard Gigabit Ethernet equipment.

Highlights

  • Extend network up to 20 km over single-mode fibre
  • Gigabit Ethernet over RJ-45 and SC ports
  • Plug-and-play setup with auto-negotiation
  • LED indicators show link, activity and power status
  • Operates reliably from 0 °C to 60 °C

Questions about this item

Does the converter fit in a standard desktop space?

The compact modular design is intended for narrow desktop locations to save space.

What is the correct order for connecting the fibre and copper cables?

Plug in the optical port first, then the UTP port, and the unit will begin working immediately.

How far can the single-mode fibre link reach before a module swap is needed?

The built-in 1310 nm single-mode module supports distances up to 20 km (12.42 miles).
