Fiber to Ethernet Media Converter

This BFKK media converter bridges a gigabit SFP transceiver to a copper RJ45 link. It lets installers extend a network over fibre without replacing existing copper switches or endpoints. The unit is a new audio/video accessory designed for straightforward deployment.

SFP Transceiver Distance Support

The open SFP port accepts multi-mode modules reaching 550 m and single-mode modules reaching 20 km. The RJ45 side runs at 10/100/1000 Mbps with auto-negotiation, MDI/MDI-X crossover and full or half duplex operation.

Installers Needing Simple Fibre Extension

Suits technicians who need a plug-and-play fibre-to-copper link with jumbo frame support and IEEE 802.3 compliance. Not for buyers who require managed switching features, PoE injection or redundant power inputs.

Questions about this item

How far can the SFP port actually reach with a single-mode module in a live link?

A single-mode 1000Base-LX module drives the link up to 20 km; multi-mode 1000Base-SX reaches 550 m.

What Ethernet standards does the RJ45 port negotiate and what speed ceiling applies?

The port auto-negotiates 10/100/1000 Mbps, full or half duplex, with MDI/MDI-X crossover, capped at 1000 Mbps.

What physical space and cooling does the metal enclosure need on a desk or rack shelf?

The case has cooling holes on two sides and requires only enough clearance for airflow around the metal housing.
