Small rectangular SFP+ transceiver module with LC single-mode port and side label

Axiom

Axiom SFP-10G-ERBD-D-AX SFP transceiver 10GBase-BX40-D 40 km 1330 TX 1270 RX nm

SKU CH-CBF9-D8E43 MPN SFP-10G-ERBD-D-AX

10 Gigabit Ethernet SFP+ transceiver with LC single-mode optics reaching 40 km using 1330 nm TX and 1270 nm RX wavelengths

  • 10GbE throughput over a single fibre strand
  • 40 km reach on single-mode LC cable
  • 1330 nm TX and 1270 nm RX wavelength pairing
  • MSA and RoHS compliant for broad switch compatibility
  • Limited lifetime warranty from the manufacturer

Axiom 10GBase-BX40-D SFP+ Transceiver

This Axiom SFP+ transceiver module operates at 10 Gigabit Ethernet speeds over single-mode fibre. It is designed as a compatible equivalent to the Arista SFP-10G-ERBD-D for network links up to 40 km.

Installation and pairing

The module uses a standard LC single-mode connector and plugs directly into an SFP+ port. Correct operation requires a matching counterpart at the remote end transmitting at 1270 nm and receiving at 1330 nm; mismatched wavelengths will prevent the link from establishing.

Wavelength pairing 1330 TX / 1270 RX

This transceiver transmits at 1330 nm and receives at 1270 nm. You must verify that the opposite side of the link uses the complementary 1270 TX / 1330 RX wavelength pair, otherwise the connection will not work.

Highlights

  • 10GbE throughput over a single fibre strand
  • 40 km reach on single-mode LC cable
  • 1330 nm TX and 1270 nm RX wavelength pairing
  • MSA and RoHS compliant for broad switch compatibility
  • Limited lifetime warranty from the manufacturer

Questions about this item

How do I verify the Axiom SFP-10G-ERBD-D-AX is working after inserting it into my Arista switch?

Check the switch port status for a 10GbE link up and confirm the optical diagnostics show a 1330 nm TX and 1270 nm RX wavelength pair within the 40 km single-mode range.

What comes in the box with the SFP-10G-ERBD-D-AX and what must I buy separately?

The package contains one Axiom SFP+ transceiver module with an LC single-mode interface; you must supply compatible LC single-mode patch cables and an Arista switch with an open SFP+ slot.

Which version should I choose if I need the matching upstream wavelength for my existing 1270 nm TX link?

Select this D variant because it transmits at 1330 nm and receives at 1270 nm, pairing with a U module that uses the opposite wavelengths on the same 40 km single-mode fibre.
