Huawei optical transceivers and pluggable optics

Optics carry readable designations giving form factor, rate and reach. Line and interface cards use the CR prefix, where the following characters encode the router chassis family and the card's function, and LPU or LPUI with a numeric suffix indicates a line processing unit and its forwarding capacity. Codes such as ET1D2S08SX1E identify interface cards by port count and type — in that example eight 10G SFP+ ports alongside 1G ports. The eight-digit 0303x code remains the definitive ordering reference for both optics and cards.

Say plainly whether you need the optic, the card, or both. For optics, give form factor, rate, reach, wavelength and the platform they must be coded for. For line cards, give the chassis model, the slot, the required forwarding capacity and the interface count. Huawei platforms enforce optic coding at the port, so an uncoded module will typically be refused. Export screening applies per transaction.

Current QSFP28 and SFP28 optics remain in production. Older SFP+ variants and the earlier LPU generations are surplus-market items. Coded compatible optics are available for most Huawei platforms.
