Product details

MT-RJ Simplex Coupler for Multimode Fiber

The TE Connectivity 1278017-1 is an MT-RJ simplex coupler designed to join two MT-RJ receptacles in a multimode fiber link. The almond-colored thermoplastic housing mounts to a panel via flange or snap-in clips, and the simplex configuration supports a single-fiber channel. A dust cap is included to protect the alignment sleeves when the coupler is unmated.

Panel Mounting and Dust Protection

Mounting options include both a flange and snap-in clips, giving flexibility for different panel cutouts and thicknesses. The included dust cap keeps the internal alignment sleeves free of debris during storage or transport, which matters for maintaining low insertion loss on the first mate.

Frequently asked questions

Does 1278017-1 include a dust cap?

Yes, the 1278017-1 ships with a dust cap to protect the alignment sleeves when unmated.

What is the difference between simplex and duplex MT-RJ couplers?

A simplex coupler like the 1278017-1 supports a single fiber channel (one transmit or one receive), while a duplex coupler supports two channels (one transmit and one receive) in a single housing.

Is the 1278017-1 compatible with standard MT-RJ connectors?

Yes, the 1278017-1 converts from and to MT-RJ receptacles, so it mates with standard MT-RJ connectors on both sides.
