Pair of white media converters with SFP slots and RJ45 ports, two BiDi LC transceiver modules, two power adapters, and a manual

BFKK

BFKK 1.25Gbps Gigabit Bidi Media Converter Pair 30km

SKU CH-6X6Y-7RKEP

A pair of media converters extends Gigabit Ethernet over single-mode fibre up to 30 km with included BiDi SFP modules

  • Pair of media converters extends Ethernet up to 30 km
  • 25 Gbps BiDi transceivers included for single-mode fibre
  • Auto-negotiation 10/100/1000 with MDI/MDIX crossover
  • Jumbo frame support up to 9K bytes for efficient throughput
  • Wide 100-240 V AC input with UL certified power supplies

Pair of Gigabit Bidi Media Converters

This set provides two single-mode fiber converters with matching BiDi SFP transceivers included. Each unit bridges a copper RJ45 port to an SFP slot at 1.25Gbps over 1310-nm wavelength. The kit is aimed at installers extending LAN links between buildings or cabinets up to 30km without running new copper.

Practical limits of the single-mode link

The fiber segment reaches 30km on standard SMF while the copper side covers 100m on Cat.5e UTP or STP. Auto-negotiation handles 10M, 100M or 1000M speeds with full or half duplex and MDI/MDIX crossover. Jumbo frames up to 9K bytes pass through and the operating window spans 0°C to 60°C.

Replaces separate transceivers and converters

Buying matched BiDi modules and media converters separately adds cost and compatibility risk; this paired kit eliminates both. The jump is worth it when a point-to-point link over single strand fiber is needed and the 30km range fits the route. It does not suit multi-mode fiber plants or distances beyond the rated reach.

Questions about this item

Should I choose the single-mode 30 km pair or a different reach?

This listing supplies a matched pair of single-mode converters with 1310 nm BiDi transceivers rated for 30 km; no other reach or wavelength option is included in this package.

What does the 1.25 Gbps headline speed mean on my LAN?

The converters handle 10/100/1000 M auto-negotiation on the RJ45 side and 1000Base-SX on the fibre side, so a 1 Gbps Ethernet link runs at line rate across the 30 km single-mode span.

Which fibre interface and standard limit the distance?

LC single-mode connectors with IEEE 802.3z 1000Base-SX optics set the practical reach at 30 km over OS2 fibre.
