Huawei storage optical transceivers and AOCs (23 P/Ns)

A small group with a wide speed range

This list is short — 23 part numbers — and it covers eight line rates from 8.5 Gbit to 200 Gbit. That is not an accident of cataloguing: optical transceivers are the component most tightly bound to the port they plug into, so every port generation needed its own part, and each one is speed-locked to that port.

Speed-locking is the single most important fact on this page. A transceiver does not negotiate down to a slower port. A 25G module in a 10G cage either does not come up or comes up in a degraded mode that is not supported. Match the rate before you match anything else.

Reach decides the optic, not the speed

Two transceivers at the same line rate can differ by a factor of several hundred in reach: 0.1 km 9, 0.3 km 3, 10 km 3, 0.015 km 3, 0.15 km 2, 2 km 1, 0.003 km 1. The reach is set by the laser, the fibre type and the receiver sensitivity, and it is not adjustable. Buying a longer-reach optic than you need is not a safety margin; on short multi-mode links it can saturate the receiver.

Multi-mode and single-mode are not interchangeable

The split in this list is Multi-mode 11, Not stated 7, Single-mode 4, Copper (RJ45) 1. Multi-mode optics use 850 nm vertical-cavity lasers and short reaches; single-mode optics use 1310 nm or longer and reach kilometres. The connector can look the same (LC appears on both) and the module will physically fit either patch cord — which is exactly why this mistake keeps happening in the field.

• A multi-mode optic on single-mode fibre will not reach its rated distance.
• A single-mode optic on multi-mode fibre will usually not come up at all.
• Patch-cord colour is a convention, not a guarantee. Read the module, not the cord.
• OM3 and OM4 differ in reach at 100G. The description says which one the module was rated for.

LC and MPO are a port-density decision

15 rows use LC and 4 use MPO. LC is a two-fibre duplex connector; MPO is a multi-fibre connector that carries parallel lanes for 40G, 100G and 200G. They are not adapters of each other: changing connector family means changing the patch panel, the trunk and often the cassette.

What the -001 and -003 suffixes mean

7 of the 23 part numbers carry a three-digit suffix. In Huawei catalogues this is a revision or packaging variant of the same transceiver: same optics, same reach, same connector, different manufacturing revision. In practice the base number and the suffixed number are usually interchangeable, but we list them separately because the catalogue does, and because a system that was qualified against one revision may report the other as an unknown part.

• Treat the suffix as a revision, not a different product.
• If your inventory system matches exact strings, keep the exact string.
• If you are replacing a failed unit, the base number is normally the right thing to search for.

Active optical cables are in this group too

3 rows are AOC assemblies rather than pluggable transceivers. They are listed here because they perform the same function, but they are a different purchase: the length is fixed at manufacture and cannot be changed later. For a fixed run inside a cabinet an AOC removes two connectors and two failure points. For a run that may be re-routed, it does not.

Copper still has a place

At least one part here is a 10GBase-T SFP module with an RJ45 connector, rated for a short run on Cat6a or Cat7 cabling. Copper modules are the simplest way to put a 10G port on existing twisted pair, and the most common source of confusion, because they look like an optical SFP and behave like an Ethernet port.

Full part-number list, 23 P/Ns

Every row carries the official description including wavelength, line rate, transmit and receive power, connector and reach where Huawei publishes them. Those four figures are what a link budget is calculated from, so we do not summarise them away.

Matching a transceiver: the order of checks

• Line rate must match the port. There is no negotiation down.
• Fibre type must match the optic: multi-mode or single-mode.
• Reach must be at least the run length, and not wildly more.
• Connector family must match the patch panel: LC or MPO.
• Wavelength must match the far end. 850 nm talks to 850 nm.
• If the far end is a different vendor, check the module is coded for an open or compatible port.

Frequently asked questions

Can a 25G transceiver work in a 10G port?

No. Transceivers are speed-locked. A faster module in a slower cage will not operate as a 10G link.

Can I use a single-mode optic on multi-mode fibre?

Generally no. The fibre geometry and the launch conditions differ; the link will not come up reliably, if at all.

Is a longer-reach optic always safer?

No. On short multi-mode links an over-specified receiver can saturate. Match the reach to the run.

Are -001 and base part numbers interchangeable?

They are normally revisions of the same transceiver. Confirm against your inventory system if it matches exact strings.

Do I need to order patch cords separately?

Yes. Transceivers and AOCs are listed here; patch cords and trunks are separate part numbers.
