TACTICAL FIBER OPTIC CABLE ASSEMBLIES
Radiall produces high-quality tactical cable assemblies for a wide range of demanding military and field applications. Two main technologies exist in fiber optic connections for tactical environments: Physical Contact (PC) technology and Expanded Beam (EB) technology. Radiall will use the best of both alternatives to deliver ruggedized and field-deployable cable assemblies.
Tactical cable assemblies operate in unstable and severe environmental conditions, such as in radars, military radio communication, intercom systems and many other applications.
Typical requirements for tactical applications:
- Fast and trouble-free integration in the field
- Easy to use and trouble-free maintenance
- Extremely high mating durability
- Less sensitivity to pollution, dirt, and dust
- Ruggedized connection, high resistance to crushing and shock
- High tensile strength
Typical FO connectors for tactical cable assemblies:
- EB Tactical MIL-DTL-83256/20 & 21 connectors
- MIL-DTL-38999 type connectors with LuxCis® ARINC 801
- Ruggedized LC, SC, and ST
RF Coaxial Connectors
Connectors featuring a “snap-on” coupling mechanism are easily connected with a straight push and unmated with a straight pull. They are well-suited for connections in limited spaces or dense environments.
Radiall offers a broad range of standard and proprietary snap-on series. The most popular snap-on interfaces are SMB and MCX. One of the main benefits of snap-on connectors is their 360-degree rotation, which makes it easy to connect and orient a right-angle plug to a receptacle. It can be easy to accidentally unmate snap-on connectors by pulling on the cable or connector, which can be seen as a weakness.
Snap-on interfaces are sometimes proposed as “slide-on” types. To connect, simply push the male and female connectors together; mating is then maintained by spring-finger friction. Slide-on versions are useful when connectors must be mated and unmated frequently; this is the case for test and evaluation.
Quick-Lock and Secure connectors are designed to provide the ease of use of a Snap-on type with the reliability of a Screw-on type. They feature a coupling mechanism that makes connections fast, simple, and reliable, in the tightest spaces and without tools.
Quick-Lock types are typically 10 times faster to mate than standard Screw-on connectors and eliminate the need for a torque wrench. They feature low engagement force and enable higher interconnection density. They allow for 360° cable rotation after installation which makes cable routing much easier.
Quick-Lock and Secure connectors are optimized for shock and vibration resistance for harsh environments, and to prevent from unmating accidentally.
Screw-on connectors provide a robust connection with high electrical performance. They are typically longer to install compared to Quick-Lock types and do not allow high-density connections.
They are preferred for test and measurement applications at very high frequency up to 67 GHz, but are also used in many applications from telecom to military.
Most screw-on series require a wrench tool to apply the right torque.
The most well-known Bayonet type connector is the BNC connector, which was initially introduced to make it easy to connect and disconnect, in comparison to screw-on connectors. The BNC series is still very popular for low-frequency test equipment. It has been made available in multiple versions, 50 and 75 ohms, high voltage, isolated, twinax, etc.
These connectors are developed for Board-to-Board and board-to-module RF interconnections. They have grown in popularity in the wireless telecom market due to the need for miniaturization. Over time, engineers are replacing bulky RF cable assemblies with simple Board-to-Board RF connectors that are able to handle power levels exceeding 100 W. This provides space, weight, and cost savings.
The product line has evolved from accommodating limited misalignment between PC boards to offering the widest tolerances available in radial and axial directions, as well as coping with varying spacing between boards.
The range also includes innovative compression RF Board-to-Board connectors designed as one-piece connectors for very short distances between PC boards.
Blind mate connectors are designed for use in rack and panel or module to module interconnections, where multiple RF connectors need to be mated simultaneously in blind mate conditions. The blind mate connector has self-aligning features that allow for misalignment when mating. Blind mate RF connectors are mating either via a sliding or snapping action. They can operate at high frequency and typically achieve high electrical performance and high reliability.
Hermetically sealed RF connectors are used to carry microwave signals in and out of an electronic package and to ensure no outside elements – including liquid, air, or gas – can enter or leak. They are designed with a fused glass-to-metal seal soldered into the connector body and sealing the connector internally. Low-loss special glass is used for the best electrical performance. Hermeticity is typically defined as a leak rate of less than 1×10-8 cc/sec of Helium at 1 atmospheric differential pressure.
Hermetic connectors are used for applications requiring an extremely rugged and reliable seal in high-pressure environmental conditions. Hermetically sealed connectors are available with many interface types, the most popular one being the SMA type.
High Voltage connectors are designed to allow signal transmission with high voltage ratings without safety risk for the operators. They are mainly used in imaging inspection, test & measurement, medical and aerospace applications. They manufacture a large range of High Voltage connectors rated from 5KV up to 20KV.
