In June 2026, the world's first S+C+L three-band ultra-low-loss multi-core optical cable was officially completed and put into operation in Qingdao, Shandong Province. This four-core fiber optic line, independently designed by domestic telecommunications companies and optical cable manufacturers, is the first to extend ultra-low-loss characteristics from the C and L bands to the S band, achieving a single-fiber capacity more than five times that of traditional optical fibers. This marks the transition of multi-core fiber optics from the laboratory to real-world network deployment.
The advantages of multi-core fiber optics are obvious: accommodating multiple independent fiber cores within a standard cladding significantly increases transmission density while saving pipeline resources. However, its engineering challenges are equally prominent—how to accurately align and perform low-loss fusion splicing of multiple fiber cores at the micrometer scale? This requires specialized equipment.
The S-22 multi-core fiber optic fusion splicer launched by Shinho Optics Ltd. is the core tool for addressing this challenge. This equipment is optimized for splicing multi-core optical fibers and can currently stably splice 150μm cladding fibers, covering various fiber core structures including 2-core, 4-core, 6-core, 7-core, and 8-core. Whether it's parallel splicing in a four-core cable or more complex seven-core and eight-core fibers, the S-22 can achieve high-precision splicing.
Technically, the S-22 multi-core fiber fusion splicer employs dual-end-face imaging and dual-mode alignment technology, simultaneously observing the fiber end face and side face before splicing to ensure accurate positioning of each fiber core. Through a precision feed system and real-time arc calibration, splicing loss is controlled to an extremely low level. Fully automatic operation, a windproof design, software upgrades, and data export functions also make it more suitable for the practical needs of current network construction.
The large-scale deployment of multi-core optical fibers relies heavily on the support of splicing equipment. The Shinho S-22 is compatible with 150μm narrow-diameter multi-core fibers and flexibly supports splicing from 2-core to 8-core, providing a reliable technical foundation for current and next-generation multi-core optical cable projects. With the S+C+L three-band multi-core line first implemented in Shandong, the commercialization of multi-core optical fiber has begun, and fusion splicing equipment like the S-22 is an indispensable part of this path.
