TNFBDCCASE01

TNFBDCCASE01 is an equipment case for Huawei transmission equipment, for the OSN 1800 occupying 1U. Mechanical items are the least interesting part of a transmission order and among the most likely to hold one up, because they get specified last and often have the longest lead times.

It occupies 1U of rack height and is fan-cooled, so clearance and filter access need allowing for. It includes fibre storage, which is more useful than it sounds: slack fibre with nowhere to go is the usual reason patch leads end up bent past their minimum radius.

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 confirm before ordering. The rack standard, the height and depth available in the room, the door and lift access on the way to it, the power feed, and the shelves this has to hold. Lead times on mechanical items are frequently longer than on the electronics that go in them, which makes this the part of the order worth settling first rather than last. Tell us what the node has to contain and the constraints of the room and we will specify the enclosure, the power arrangement and the installation materials together.

Green Code Technologies supplies Huawei transmission equipment together with the racks, power, cabling and installation parts that go with it. 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 site, the power available there and what the node has to contain and we will come back with a straight answer.
