Why military platforms use fibre MIL connectors
Tanks, helicopters, submarines and command systems have to share data, video and commands quickly and securely. Copper wiring suffers from heat, dust, water and vibration, and its signals can be disturbed by electrical noise. A fibre optic MIL connector carries the signals as light, which is immune to interference, inside a rugged plug that is sealed against dust, water and heat.
The connector allows rapid insertion and extraction, even under difficult conditions. Because the termini can be removed from the rear, a damaged channel can be serviced without replacing the whole connector.
Stated features
| Feature | What it means for the user |
|---|---|

Questions buyers ask
How are fibre MIL connectors better than standard connectors?
They protect the fibre joint inside a rugged, sealed shell, so the connection survives heat, rain and physical shock that would damage a standard connector.
What temperature range does the MIL connector cover?
It is rated from -55 °C to +200 °C, for use in arctic cold and desert heat.
What does genderless mean?
Both sides of the connection work the same way, so there is no male or female end to match.
Is the connector easy to clean?
Yes. Remove the front cap to reach the termini for cleaning, and connect or disconnect quickly afterwards.
Can Radix make a custom MIL connector?
Yes. Custom connector options are made to order. Contact Radix with your channel count, mounting and cable details.
