Downstream 10 Gbps SFP+ transceiver

The module delivers 10 Gbps over single-mode fiber at 40 km using 1330 nm Tx and 1270 nm Rx wavelengths. It connects through an LC duplex port and is hot-swappable for zero-downtime insertion. The unit draws less than 1.6 W and carries an MTBF of 646156559 hours.

Brocade 10G-SFPP-BXD-40K replacement

This transceiver is programmed and tested as a direct drop-in for the Brocade 10G-SFPP-BXD-40K part. It pairs with the matching upstream module 10G-SFPP-BXU-40K-ST to complete a bidirectional 10GBase-BX link. The upgrade is worth it when existing Brocade hardware needs a qualified spare without OEM pricing.

Sustained 40 km line-rate operation

Continuous 10 Gbps throughput is maintained across the full 40 km distance with DDM monitoring active. Power draw stays below 1.6 W under constant load, keeping thermal output predictable in dense chassis. Hot-swap capability allows failed units to be replaced while traffic continues on adjacent ports.

Questions about this item

What LC single-mode patch cable and switch port does the 1330nmTx/1270nmRx 40 km transceiver need?

It requires a duplex LC single-mode fiber patch cord and an SFP+ cage that supports 10GBase-BX downstream optics; the module inserts directly into the cage and locks with the bail latch.

How is the hot-swappable SFP+ module installed, and what step do people miss?

Slide the transceiver into the SFP+ slot until it clicks, then remove the dust caps and connect the LC cables; the step often missed is keeping the bail latch closed until the module is fully seated.

When should the downstream 10 Gbps BiDi module be replaced based on its rated MTBF?

The MTBF is 646,156,559 hours; plan replacement if link errors rise, optical power degrades below the 40 km budget, or after a firmware update changes compatibility with the paired upstream module.
