Package side
s
Features
1. JIS, IEC standard compliant and intermateability test certified.
Comply with JIS C 5983 (F14 type fiber optic connectors) and IEC 61754-6.
MU intermate test by NTT certified connector.
2. Flame resistant
Satisfies flammability rating UL94V-0
3. Backplane
MU Backplane connector has a self-holding mechanism which does not transfer any force on the back panel
when both side of connector assemblies are fully connected. Back panel side connectors can be removed or
inserted even both sides are mated.
4. Wide Variety of adapter type
5. Simplified plugs and Receptacles
Extremely small size (only 13.75mm Plug length). MU simplified plug is designed for equipments inside connection.
s
Applications
Optical terminal equipment, optical relay racks, test equipment, telecommunication equipment and other systems
requiring Small Form Factor optical connections.
