About This Part
The ZTE Optical Protection Card (SOP21550) is a critical component designed to enhance the reliability and resilience of optical transmission networks. Operating within the widely used 1550 nm band, this card provides automatic fiber switching and link protection capabilities. Its primary function is to detect failures on a primary optical fiber link and instantaneously switch traffic to a redundant backup link, ensuring uninterrupted service and minimizing downtime. In demanding telecom and data centre environments, where service continuity is paramount, the SOP21550 card is indispensable. It is typically deployed in long-haul, metro, and access networks to safeguard critical data and voice traffic against fiber cuts, equipment malfunctions, or other link degradations. By automating the protection switching process, it significantly reduces manual intervention and accelerates recovery times, which is crucial for meeting stringent Service Level Agreements (SLAs). Revo Distribution Limited offers this ZTE Optical Protection Card (SOP21550) as part of our extensive inventory of used and refurbished telecom and data centre equipment. Providing high-quality, tested refurbished components like the SOP21550 allows network operators to cost-effectively maintain, upgrade, or expand their existing infrastructure, ensuring robust network resilience without the capital expenditure of new equipment.
