Sumitomo Electric, Senko partner on AirMT noncontact multi-fiber connector technology

New fiber-optic connectors are based on a Sumitomo-developed noncontact multi-fiber optical ferrule technology that the company has licensed to Senko.

The AirMT connector series lineup is being offered initially in two formats: the FlexAirConnecT (left) and AirMT MPO (right).

Sumitomo Electric Industries, Ltd. and Senko Advanced Components have partnered to introduce the AirMT multi-fiber optical connectors. The AirMT is billed as offering an alternative to physical contact multi-fiber optical connectivity, as found in such formats as MPO connectors.

The traditional MPO connector, the partners observe, requires high spring force to achieve physical contact for MT-to-MT ferrules, and suffers from high sensitivity to dust contamination. This contamination problem is exacerbated by the difficulty in ensuring a pristine condition for the fiber endface, the companies add.

The AirMT offers an insertion loss of <0.5 dB and return loss of <55 dB (guaranteed in the FlexAirConnecT housing, one of two initial formats alongside MPO housing; see photo above), which Sumitomo and Senko say are comparable to the regular physical contact MPO connectors.

The fiber-optic connectors are based on a Sumitomo-developed noncontact multi-fiber optical ferrule technology that the company has licensed to Senko; the AirMT name is a jointly registered trademark of the two companies.

The partners see the AirMT fiber connectors finding use for in-equipment fiber management and backplane, as well as harsh environments with high levels of vibration. Learn more about the product.
