Huawei OptiX OSN 1800 II Compact

Huawei OptiX OSN 1800 II Compact is a Huawei OSN 1800 system, 2U high, supplied as a configured node rather than as individual cards. Buying at this level means the shelf, its control and cross-connect, its power arrangement and a defined set of interfaces arrive as one item.

Huawei’s own description of the platform is worth reading in full on the specification tab, but the short version is that this is positioned as an OTN platform, built around optical transport rather than SDH, which is the architecture the industry moved to for high-rate transport. Matching the platform to the traffic you actually have matters more than the headline capacity, because a packet platform asked to carry a lot of TDM, or the reverse, works but works awkwardly.

Where the OSN 1800 stands today is better than the part number suggests. This is a current Huawei platform, not a legacy one. The OSN 9800 line was refreshed as recently as 2024 and Huawei still describes its newest member as a flagship WDM product, and the OSN 1800 is the metro counterpart in the same generation. A card for one of these is a card for a line that is still being developed rather than one being wound down.

The honest caveat is practical rather than commercial. Huawei does not publish end-of-support dates outside a logged-in support account, so nobody selling you this part, ourselves included, can quote you a hard support-end date. What can be said is that the platform is current and the part is not an orphan.

One UK rule worth knowing about, and who it actually binds. Under the UK’s Designated Vendor Direction, designated public telecoms providers, meaning the large operators running public networks, were required to stop using Huawei high data rate transmission equipment in their core networks from 31 December 2025, a date that has now passed, and must remove Huawei from their 5G networks entirely by 31 December 2027.

If you are one of those operators, that is the governing fact about this product and nothing here changes it. If you are not, and most buyers of transmission hardware are not, the Direction does not apply to you and there is no UK legal barrier to buying or running this equipment. It is narrowly scoped to designated providers and public networks. Worth stating plainly, because it gets quoted as though it were a blanket ban, and it is not.

What to settle before ordering a complete system. The power feed available at the site and whether there is battery behind it; whether the configuration is protected; the interfaces the traffic actually needs now and in a few years; and the licences, because on Huawei transmission platforms capacity and ports are frequently licensed separately from the hardware that provides them. A node physically capable of a rate it is not licensed for looks like a fault and is not one. Tell us the site, the traffic and the availability you have promised and we will configure it properly, including the licences and the installation materials that are easy to leave off a quote.

Green Code Technologies supplies Huawei transmission hardware, including line and tributary boards, cross-connect and control cards, optics and the shelves they go in. We are a supplier of Huawei alongside HPE, Dell, Cisco, Samsung and Netgear, and we would rather confirm a part against Huawei’s own documentation than sell you the wrong one, which on OSN 1800 equipment is worth doing. Send us the platform, the subrack and the software release and we will come back with a straight answer.
