Huawei TN21PIU – Power Interface Unit board for the Huawei OptiX OSN optical transport platform. Tech-Star (UK-based, shipped worldwide).

The Huawei TN21PIU is a Power Interface Unit (PIU) board used within Huawei’s OptiX OSN series of optical transmission platforms. Sibling PIU boards such as the SSN1PIUB (OSN optical transport family) and TN51PIU/TN11PIU02 (OSN 8800/OSN6800) are documented Huawei power interface cards that connect the subrack to the site’s external -48V DC power feed and distribute it internally to the chassis’s service and control boards, while also providing power-related alarm and monitoring functions. As a slot-in board rather than a standalone power supply, the PIU sits within the OSN subrack’s dedicated power slot(s) alongside the system control and cross-connect boards. OptiX OSN platforms are widely deployed by network operators for SDH, WDM, and OTN optical transport across metro and backbone networks. Tech-Star (UK-based, shipped worldwide) supplies tested Huawei optical transport boards for engineers maintaining OptiX OSN deployments.
