MOC Series

The MOC connector is Kyomori-Ka’s latest optical communication product; optimized for direct equipment connection, it delivers a robust interface with high debris resistance. It supports stacked optical fiber ribbons, and its 64-channel design enhances fiber density and spatial efficiency, with future versions set to accommodate single/multi-port and front/backplane configurations.
Achieve up to 48 channels using stacked 12-channel ribbon fibers, or up to 64 channels using stacked 16-channel ribbon fibers. Capable of terabit-per-second bandwidth: 64 single-mode fibers at 25 Gbit/s equals 1.6 Tbit/s per connector.
The product is compact and dense; due to the minimal number of components and the fact that fiber polishing is not required during assembly, the cost is lower.
The alignment tolerance for the connector mating plane is generous, thereby ensuring consistently low insertion loss and return loss.
Expanded beam technology significantly reduces signal sensitivity to debris.
Low insertion force facilitates high-volume mating in high-density applications.
Stacked ribbon configuration increases density and maximizes space efficiency.
Available in jacketed or bare ribbon configurations.
A spring force of 3.1 N is sufficient.

Product Features




1. The alignment precision requirements for the optical interface are relaxed. A 3 μm misalignment in a single-mode fiber (1310 nm wavelength, MFD 9.2 μm) results in 1.8 dB of attenuation, whereas an expanded-beam interconnect (90 μm collimated beam spot, Gaussian distribution) experiences only 0.01 dB of attenuation for the same misalignment; this relaxation of precision standards offers new options for precision alignment.
2. Free-space interconnection eliminates the need for physical contact between fiber end-faces; by removing the need for end-face structure control, simplifying the manufacturing process, and reducing mating pressure, it significantly lowers the cost of high-density multi-fiber interconnection.
3. Spreading the signal over a larger area minimizes the impact of signal obscuration and attenuation caused by physical contact losses, thereby reducing the effects of debris.
