The OPTOKON HMA series hybrid field optical patch cord is a specialized cable-connector solution for tactical and field networks, providing both optical signal transmission and power/data delivery simultaneously. In other words: one cable — two functions.
Main Features
- Suitable for military field systems, mobile communication nodes, FTTA (antenna installation), and video surveillance systems.
- Consists of a hybrid cable: 2 optical fibres + 3 copper conductors (AWG 16), allowing simultaneous transmission of video/data and power.
- The connector complies with the military standard MIL-DTL-38999, providing enhanced durability and protection, and withstands harsh environments.
- Operating temperature range: from -40 °C to +70 °C.
- Optical connection technology: Expanded Beam, which increases resistance to contamination, moisture, and mechanical impact.
Comparative Specifications of Models
The HMA series has several modifications, including HMA-S (supports up to 8 fibres), HMA-M, and HMA-J. The table compares key characteristics.
Model | Optical fibres | Copper conductors | Application | Comment |
HMA-M / HMA-J | Up to 4 fibres (single-mode or multimode) | — | Less complex tactical connections | May be without copper conductors |
HMA-S | Up to 8 fibres | 3 copper conductors (AWG 16) | Full-functional hybrid networks (data + power) | The most versatile version |
Model Features
- HMA-S: cable specifically designed for mobile devices, robotics, and environments with high vibration or movement.
- Connector variants: plug and receptacle/panel — convenient for panel mounting or use in mobile units.
- Optical loss: less than 0.7 dB for multimode and less than 1.0 dB for single-mode connections.
FAQ (Questions / Answers)
Q1: What applications is the HMA series intended for?
A1: For military field networks, mobile communication nodes, FTTA (antenna installations), video surveillance systems, robotics — anywhere optical transmission and power are needed simultaneously.
Q2: What is the difference between HMA-S, HMA-M, and HMA-J?
A2: HMA-M and HMA-J are designed for fewer fibres (up to 4) and may be without copper conductors; HMA-S supports up to 8 fibres + 3 copper conductors, making it more versatile.
Q3: What type of optical connection is used?
A3: The Expanded Beam technology is used, ensuring low loss and better resistance to contamination and mechanical impact.
Q4: What are the operating temperature conditions?
A4: The product withstands temperatures from -40 °C to +70 °C.
Q5: Can the cable be repaired in the field?
A5: Yes — the design provides high durability and the ability to install/repair in the field, suitable for mobile and moving systems.
Q6: What types of connectors are available?
A6: Plug and receptacle/panel versions are available, allowing integration into cables, panels, or equipment.
Features and Advantages:
- Flexible design: the cable and connectors are engineered for operation in field combat/transport systems.
- Hybrid design: a single cable transmits both data (optics) and power or control signals (copper), saving space and reducing the number of connectors.
- Enhanced reliability: Expanded Beam technology increases service life and reduces connection losses.
- Wide temperature range: suitable for harsh environments from -40 °C to +70 °C.
- Flexible installation: supports moving objects, vibration, and mechanical dynamics.
- MIL-DTL-38999 military-grade standard ensures compatibility with military and tactical systems.
