The MU incorporates the positive mechanical and optical performance
features of the SC style connector in a high density small form factor (SFF)
design. The miniature unit-coupling MU is currently recognized by the IEC
International standard organization.
This fiber optic connector system features a compact connector housing
and a ø1.25 mm diameter ferrule.
The MU is available as a Simplex or Duplex connector for both Single Mode
(PC or APC) and Multimode applications.
Diamond, leveraging its experience in SFF connector design and
manufacturing, has incorporated its unique ferrule design and proprietary
active alignment process which has made their own E-2000™ & F-3000™
connectors recognized performance leaders. The end result is an MU
connector with superior optical performance.

As standard, Diamond uses colored connector bodies, cable boots and mating adapter housings to identify the fiber type
(SM or MM 50/62.5µm) and ferrule polish (PC or APC).
Diamond`s standard connector/boot/adaptor colors are as follows: Beige/ Black/Beige for MM PC 50µm, Beige/Beige/Beige for MM PC 62.5µm, Blue/Blue/Blue for SM PC, and Green/Green/Green for SM APC. Other colors are available upon request.
Please refer to the Simplex, Duplex, Multiple fiber Assemblies order form for standard duplex channel identification.
