BFKK

BFKK 10 Gigabit SFP to 10G RJ45 Converter video accessory

SKU CH-2SYX-Y4YFS

Converts 10G SFP+ fibre to 10G/5G/2.5G/1G/100M copper with auto-negotiation and plug-and-play operation

  • Auto-negotiates 10G/5G/2.5G/1G/100M speeds on the RJ45 port
  • Accepts any 10GBASE-X SFP+ module plus 1G rate modules without lock-in
  • Works instantly — just add power, an SFP module and cables, no setup required
  • Front-panel LEDs show power, SFP link and RJ45 link status at a glance
  • Compact metal enclosure with wall-mount ears and vented sides fits tight equipment boxes

Fiber-to-Ethernet media conversion

The BFKK converter translates a 10G SFP+ optical link into a copper RJ45 port, letting devices without SFP cages join a ten-gigabit backbone. It accepts standard 10GBase-X modules and also works with 1G transceivers, so the same box can serve mixed-speed environments. Power, SFP and RJ45 LEDs show link status at a glance. No software setup is required; the unit negotiates speed automatically once cabled.

Replaces separate transceivers and switches

Instead of buying a dedicated SFP+ switch or multiple fixed-speed media converters, this single unit handles 10G, 5G, 2.5G, 1G and 100M rates through auto-negotiation. The jump is worth it when you need to extend a fiber run to a desktop, server or NAS that only has an RJ45 jack. Note that 10G operation requires Cat6a cabling; slower speeds will fall back on lesser grades.

Fits wall-mount or rack installations

The compact metal enclosure has cooling vents on both sides and includes mounting points for walls, equipment boxes or computer-room racks. An external power supply connects to the barrel jack, freeing internal space in crowded cabinets. MDI/MDIX auto-crossover removes the need for crossover patch cords, simplifying cable management in home, commercial or industrial deployments.

Questions about this item

What cable category is required for the 10 Gbps RJ45 port on this converter?

The 10 Gbps RJ45 port requires a Cat6a network cable to achieve full 10G speed, while lower speeds will negotiate automatically on lesser cables.

Does the SFP+ slot need any configuration before use with a compatible module?

No configuration is needed; simply connect the power supply, insert the SFP module, link the fibre and Ethernet cables, and the converter operates immediately.

How does the metal enclosure handle heat during continuous operation?

The metal case has cooling holes on both sides to dissipate heat passively without requiring a fan or active maintenance.
