HMA-S Series connector

HMA-S Series connector

The OPTOKON HMA-S connector series, a large size „Expanded Beam“ connector is designed for connection of the nodes of harsh environmental network by the help of cables with optical fibers. The used expanded beam technology preservers all advantages of signals transmission through the optical lines in field harsh environmental conditions. Additionally to ruggedized optical networks the HMA-S is suited for a vast array of applications, like heavy industry connections, petrochemical application, broadcasting temporary optical lines. The innovative designs ensure its ability for deployment in the toughest environments where high performance and total reliability are critical. Benefiting from expanded beam technology the precision optical alignment system creates immunity from water, mud, dust oil and other contaminants. The HMA-S Hermaphroditic coupling eliminates the need for adaptors and male and female mating halves. Hermaphroditic housings allow for rapid deployment, creating low loss Single mode and Multimode daisy chained links in a variety of planforms ranging from simplex fiber to a four fibers. The OPTOKON HMA-S is ideally suited for environmental extremities where low maintenance and quick repairability is necessary.
