Huawei 021SJC SSN2PQ1B03 optical interface board for OptiX OSN transmission systems.

The Huawei 021SJC is an SSN2PQ1B03 optical interface board designed for use within Huawei’s OptiX OSN series of optical transmission network equipment. This card provides STM-1/STM-4 optical processing capabilities, enabling efficient multiplexing and transmission of traffic across SDH/SONET optical transport networks.

This board is deployed within Huawei OptiX OSN 1500, OSN 2500, or OSN 3500 series platforms, serving as a key component in metro and backbone optical transport networks. It supports telecommunications carriers and enterprise networks requiring reliable, high-capacity optical connectivity for voice, data, and video services.

The SSN2PQ1B03 represents Huawei’s established SDH optical transmission technology, which remains in active use across many legacy carrier networks worldwide. As operators maintain existing infrastructure alongside newer technologies, spare and replacement boards remain essential for network continuity.
