Fiber Shuffle-Product-DYS FIBER OPTIC LIMITED

Fiber Shuffle

Fiber Shuffle Optical Flex Board is a high-density optical interconnection component. Adopting high-temperature resistant PI flexible substrate and integrated embedded fiber technology, it eliminates the messy wiring of discrete fibers. The product enables shuffle-style cross routing and equal-length fiber layout according to customized optical topologies. Pre-terminated with high-density connectors including MPO/MTP/MT, it integrates multi-channel optical paths in one assembly. Supported by over 100 proprietary patents, it supports hybrid layout of single-mode, multimode and polarization-maintaining PANDA fiber, efficiently solving high-density wiring issues inside AI switches and CPO devices for lightweight and modular equipment assembly.

APPLICATION

AI high-speed datacenter switches: internal interconnection between optical engines and front panel ports for 800G/1.6T switches
CPO co-packaged optics: high-density on-board optical interconnection inside optical engines
OXC all-optical cross-connect equipment: integrated internal cross optical backplane
HPC high-performance computing: short-reach high-speed links between server boards
Military & automotive special optical communication: compact routing inside narrow equipment cavities

FEATURES

High-density integration: Hundreds up to 1200 fibers on single board, greatly saving internal cabinet space vs loose fibers
Precise equal-length customization: Controllable fiber length to reduce time delay difference and inconsistent insertion loss
Flexible bendable PI material: Minimum bend radius ≥5mm, fits irregular narrow cabinet space and avoids fiber tangling
Multi-fiber compatibility: Custom mixed routing for single-mode, multimode and PM PANDA fiber
Easy assembly: Pre-installed MPO/MTP/MT connectors for blind mating, simplifying production and maintenance
Low loss & high stability: Automated fiber fixation, full optical loss testing before delivery, excellent resistance to temperature shift and vibration
