MU-type High-Density Plug-in Optical Fiber Connectors
HMU Series
HMUB-type Fiber Connectors
s
Features
1. MU-type Correspondence
These connectors can be used with the NTT,
MU-type optical fiber connectors.
2. Plug-in Housing
The plug-in housing has a self-holding mechanism
which does not exert a pushing force on the back
panel when in the coupled condition.
3. Back Panel Side Optical Terminals
Insertion and withdrawal of back panel side optical
terminals is even possible when the back panel and
the package are in the coupled condition.
4. Wide Variation of Connectors for Junction Applications

5. Optical Terminals
The optical terminals (optical connectors) are ultra-
miniature optical fiber connectors that use the same
fastening mechanism as the SC-type optical fiber
connectors (JIS C 5973).

Applications
Optical terminal equipment, optical relay racks, mea-
suring instruments, etc.
