StarTech.com SFP-10G-BXD-I-ST — 10G BiDi SFP+, Downstream End
10 GbpsOne strandTX 1330 nmCisco coded
The StarTech.com SFP-10G-BXD-I-ST is a 10 Gbit bidirectional SFP+ transceiver coded for the Cisco SFP-10G-BXD-I. It sends at 1330 nm and receives at 1270 nm over a single strand of single-mode fibre, up to 10 km, with digital diagnostics. It is the downstream (D) end of a BiDi link, used on Cisco routers and switches where fibre strands are scarce. In practice, bidirectional optics are used where fibre is scarce — a leased dark-fibre strand, a full duct or an old building link. Before you order, confirm which end of the strand gets which module and that the fibre is single-mode all the way.
Compatibility — check before buying:
A BX-D module must face a BX-U module on the same strand. Two BXD modules will not link — order SFP-10G-BXU-I-ST for the other end. The port is a simplex LC, so you need a single-fibre patch cord. The module is coded for Cisco and StarTech.com names Cisco ASR, NCS and Catalyst 3850 platforms; it is a 10G part and will not run a 1G BiDi link. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your switch model and the cable run and we check it before you order.
Best For
✓ 10G links on a single fibre strand
✓ Leased dark fibre
✓ Cisco ASR and NCS router ports
✓ Catalyst 3850 10G uplinks
✓ Doubling capacity of existing fibre
✓ Replacing a failed BXD module
Key Features
Half the fibre
One strand carries both directions of a 10G link, so a two-strand bundle can serve two links.
One strand instead of two
A bidirectional optic sends and receives on different wavelengths over a single single-mode strand, which halves the fibre you need. The price of that is pairing: each link needs one downstream and one upstream module.
Monitoring you can read
Digital diagnostics (DDM) let the switch report temperature, laser power and received light, so a dirty connector or a failing link shows up in the switch before users call.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.

Frequently Asked Questions
Singular Expert Insight
We sell BiDi optics as D/U pairs: with the SFP-10G-BXD-I-ST, add the SFP-10G-BXU-I-ST for the far end. StarTech.com’s lifetime warranty makes these a strong alternative to OEM optics for single-strand links. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status from the switch and we help you find out whether it is the optic, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need a 10G link over one single-mode strand up to 10 km on Cisco equipment, with a BX-U at the far end.
Skip it if
Both ends are BXD, you have two strands and prefer standard LR optics, or you need 1G.
