About This Part
The Huawei SL91SL1DA04 is an essential optical interface board engineered for high-performance telecommunications networks. This board provides two Synchronous Transport Module - Level 1 (STM-1) optical interfaces, each operating at 155.52 Mbit/s. It is typically deployed in core telecom networks, metropolitan area networks (MANs), and large enterprise backbones, facilitating the transmission of high-bandwidth data, voice, and video traffic over optical fiber. Its primary function is to connect network elements, such as SDH multiplexers or cross-connects, to the optical fiber infrastructure, enabling network expansion, upgrades, or the establishment of new long-haul links. Key technical specifications include its 2xSTM-1 capacity, indicating two independent optical ports. The "L-1.2" designation refers to a long-haul optical interface standard (ITU-T G.957), signifying its suitability for extended transmission distances, often up to 40-80 km, with specific optical power budget requirements. The board utilizes LC/PC connectors, a widely adopted small form-factor fiber optic connector known for its reliability and excellent optical performance. Revo Distribution Limited carries the Huawei SL91SL1DA04 to provide network operators and data centers with reliable, cost-effective, and sustainable solutions for maintaining, expanding, or upgrading their SDH infrastructure. These refurbished boards offer a significant economic advantage over new equipment, ensuring continued operational efficiency and network stability.
