BFKK Multi-Mode LC Gigabit Fiber Media Converters 550M 850nm 2 Pack

SKU CH-VX87-QBHP4

Pair of multi-mode LC fiber media converters extend gigabit Ethernet up to 550 metres at 850 nm wavelength

  • Converts copper Ethernet to multi-mode fiber up to 550 meters
  • Includes two 1.25G LC SFP transceivers operating at 850nm wavelength
  • Auto-negotiates 10/100/1000 Mbps speeds for instant compatibility
  • LED indicators display TX, FX link, power and duplex status
  • Plug-and-play installation requires no software configuration

Multi-Mode LC Gigabit Media Converter Pair

This two-pack provides a pair of fiber media converters that extend a 10/100/1000 Ethernet link over multi-mode fiber to a distance of 550 meters. Each unit includes an LC SFP transceiver operating at a wavelength of 850 nm with a 1.25 G data rate. The converters automatically adapt to the connected network speed and are designed for plug-and-play installation without configuration.

Passive Cooling and Low Power Operation

The converters operate silently without active cooling fans, relying on passive heat dissipation for thermal management. Status LEDs for TX, FX LINK/ACT, POWER and FDX allow immediate monitoring of link activity and power status. The units draw minimal power during normal Gigabit Ethernet operation, making them suitable for continuous deployment in noise-sensitive environments such as offices or home network cabinets.

550 Meter Multi-Mode Distance Limit

The single specification that determines suitability is the maximum transmission distance of 550 meters over multi-mode fiber using the included 850 nm transceivers. This limit is fixed by the optics and cannot be extended with this hardware. Buyers who need longer fiber runs must select different transceivers or single-mode equipment not provided in this package.

Questions about this item

How do I install the BFKK media converter and what step is often missed?

Insert the included LC SFP transceiver into the converter's SFP slot, connect multimode fiber patch cables to the dual LC ports, and plug a Cat5e or better UTP cable into the RJ-45 port; the step often missed is verifying the fiber link LED shows activity before assuming the link is up.

What maintenance or replacement will the BFKK converter need later?

The LC SFP transceivers are hot-swappable and may need replacement if damaged or if you change fiber distance; keep the RJ-45 ports clean and check that the power adapter remains firmly seated.

What limit appears first when the BFKK converter runs under sustained load?

The 550-meter multimode fiber distance at 850 nm wavelength is the first hard limit; the converter auto-negotiates up to 1000 Mbps but cannot extend the signal beyond that rated reach.
