OPTOKON HMA Patch Cords — Reliable Optical Solutions for Extreme Conditions
The OPTOKON HMA product line is a series of highly reliable patch cords and connectors designed for building tactical and industrial optical networks.
Thanks to the Expanded Beam technology, HMA modules ensure stable signal transmission even in the harshest environments: dust, dirt, moisture, oil, or mechanical impact do not affect connection quality.
The series includes several models — HMA-M (Mini), HMA-J (Medium), HMA — S (Standard) and HMA Patchcord — differing in size, fiber count, and application area.
Main Features of the OPTOKON HMA Series
- Expanded Beam technology — protection from dust, water, dirt, and oil
- Hermaphroditic coupling — no adapters required, fast and simple connection
- Fast installation and repair in field conditions
- Compatible with singlemode and multimode fibers
- High resistance to vibrations, shocks, and drops
- Compliance with MIL-DTL-83526, MIL-STD 810G, AECTP-400

FAQ — Frequently Asked Questions
- How is HMA different from standard optical connectors?
Thanks to Expanded Beam technology, the contact does not require physical touch — the light beam is expanded, which protects the connection from dust, dirt, and moisture. - Can HMA be used in field conditions?
Yes, all models are designed to operate in extreme temperatures and high humidity. - Is fast connector replacement possible on-site?
Yes, the design ensures field repairability without special tools. - What is the service life of HMA connectors?
More than 3000 mating cycles without signal degradation. - Does HMA support hybrid systems (optical + electrical)?
Yes, the HMA-S series has variants with electrical contacts (Size 16, 20).
