Pair of silver SFP+ BiDi transceivers with simplex LC ports

Alphacool

Alphacool 2 in 1 Accessory 10GBASE-BX20-UD BiDi SFP+ Pair

SKU CH-BF20-F5E5X

A pair of bidirectional SFP+ transceivers for 10 Gbps links over single-mode fibre up to 20 km using simplex LC connectors

  • Bi-directional 10 Gbps link over a single fibre strand
  • Reaches 20 km on single-mode LC simplex cabling
  • Wavelength pairing TX 1270 nm / RX 1330 nm and TX 1330 nm / RX 1270 nm
  • Low power draw below 1.2 W with digital diagnostics monitoring
  • Hot-pluggable SFP+ MSA design tested for broad vendor compatibility

BiDi SFP+ Pair for 10 GbE Links

This pair of bidirectional SFP+ modules delivers 10 GbE connectivity over a single strand of single-mode fibre. Each transceiver uses complementary 1270 nm and 1330 nm wavelengths to send and receive data simultaneously. The modules suit network engineers upgrading switches, routers, servers or NICs equipped with 10G SFP+ ports.

Simplex LC Reach and Power Limits

Transmission reaches 20 km over standard single-mode fibre with a simplex LC/UPC connector. Power draw stays below 1.2 W per module, keeping thermal load low in dense chassis. Digital diagnostic monitoring is supported, but the link budget is fixed by the 20 km design target and cannot be extended without different optics.

Paired Wavelengths Decide Compatibility

One module transmits at 1270 nm and receives at 1330 nm; its partner does the reverse. This fixed wavelength pairing means the two units must be deployed together at opposite ends of the same fibre run. Networks requiring different wavelength pairs or multi-mode fibre cannot use this specific BiDi set.

Highlights

  • Wavelength pairing TX 1270 nm / RX 1330 nm and TX 1330 nm / RX 1270 nm
  • Low power draw below 1.2 W with digital diagnostics monitoring
  • Hot-pluggable SFP+ MSA design tested for broad vendor compatibility

Questions about this item

Should I order the up or down wavelength module for my link?

The pair includes both modules — one transmits at 1270 nm and receives at 1330 nm, the other does the opposite — so a single purchase covers the full bidirectional link.

What does the 10 Gbit figure mean once the module is installed in a switch?

It delivers a 10 Gbit/s Ethernet channel over a single fibre strand up to 20 km, using the 1270/1330 nm wavelength pair and digital diagnostics monitoring.

Is the SFP+ interface limited to specific switch brands?

The modules follow the SFP+ MSA and are tested for compatibility with over 100 vendors including Mikrotik, Netgear, TP-Link, Linksys, Broadcom, Edgecore, EMC, F5, Nokia, QTC and Supermicro.
