At Milestek, we provide custom-cabling, harness, and interconnect solutions for military, aerospace, telecommunications, and transportation applications. In other words — high-performance, high-demand industries that insist upon mission-critical reliability, unwavering accuracy for provided specifications, and an innovative, customizing spirit.

The custom military cables and connectors we deliver are thoroughly tested over and over again, and arrive 100 percent guaranteed to perform as expected. And we do it for coaxial, twinaxial, triaxial, serial, SCSI, 1553-B, multi-conductor, fiber optic, and D38999 cable assemblies.

Here’s how we do it:

In-house innovation and design

At our manufacturing headquarters in Denton, Texas, our in-house design and engineering staff simply live, eat, and breathe interconnectivity solutions. The keys are customization and optimization. Our custom cable designs can meet the demands of unusual, mission-specific applications, as we can also revise your existing designs to become more cost-effective.

In practice, the advantages of working with us include:

  • An unmatched connector and cable inventory.
  • Detailed drawing proofs
  • CAD design expertise
  • Prototype design and development
  • Build-to-print capabilities
  • ISO 9001:2008 and AS9100 certification

Standards and testing

Once the harnesses and interconnect solutions are designed, if we’re not fully confident in their functionality, we won’t sell them. With this in mind, thorough, determined standards and testing are key. For example, our testing capabilities include:

  • Signature Touch 1 cable analyzers and 1000RX cable analyzers
  • CAMI Research CableEye PC-based cable test systems
  • Oscilloscopes
  • Hipot testing
  • RMS bench-top multi-meters
  • Shimpo HTC 100 pull test units
  • VSWR testing using a network analyzer 3 GHz

Our products are manufactured per IPC J-STD-001D and IPC-WHMA-A 620 standards for soldering, and an in-house J-STD-001D certified trainer oversees on-going training of assembly technicians.

Experience, and a reputation you can trust

Take custom, mission-specific applications, for example. To get them right, engineers need to both understand the long, intricate history of cabling solutions, and possess the flexibility and innovative spirit needed to produce new, unprecedented solutions. Thanks in big part to our nearly 30 years of experience in the custom military interconnect solutions industry, our engineers have the experience and the foresight to do both.

Ever since our founding in 1981, we’ve been grateful to have played a role in the development of the most robust military and aerospace industries in the world. In fact, here at Milestek, we’re an approved vendor for Tier I and Tier II Defense and Aerospace companies like Raytheon, Lockheed Martin, Rockwell Collins, Honeywell, L3 Communications, GE, Northrop Grumman, and General Dynamics.

In 2008, this obsession with solutions earned Milestek the Silver Boeing Performance Excellence Award.

We’re proud to offer turnkey, one-stop shop MIL-STD-1553B solutions here at MilesTek, including the industry’s most complete line of data bus couplers for MIL-STD-1553B box-style and in-line couplers.

So here are just a few facts about the MIL-STD-1553B serial data bus worth knowing:

How was the MIL-STD-1553B standard developed?

Like much of our nation’s IT infrastructure, MIL-STD-1553 was actually designed by the military in the early 1970s as a way to replace analog point-to-point wire bundles between electronic instrumentation. In 1978, the version was upgraded to MIL-STD-1553B as a way to boost both compatibility between designs by different manufacturers and overall flexibility, through providing explicit specifics about the electrical interfaces.

For example, in the F-16 Falcon fighter jets which first featured the standard, MIL-STD-1553B helped reliably connect and integrate the weapons systems onboard with the mission computer and other applications.

Minus a handful of minor updates throughout the years since then, the data bus has remained the most popular and reliable militarized network for more than 30 years now, used most prominently in military machines like F-16 Falcon fighter jets, satellites, missiles, and the International Space Station. Commercial aircraft manufacturers have grown fond of the technology as well, thanks to a strong, mission-critical track record of excellent EMI performance, dependability, and robustness.

Cool. So how does it work?

The MIL-STD-1553B bus features four primary elements:

1. The bus controller, which manages the information flow.

2. Remote terminals that interface one or more simple subsystems to the data bus and respond to commands from the bus controller.

3. The bus monitor, which is used for data bus testing.

4. Data bus components (data bus couplers, bus cables, terminators and connectors).

Data is transmitted sequentially, bit-by-bit, and received then in a multiplexing scheme over two copper wires from computer to computer (usually at a rate of one megabit per second). In most vehicle uses for the MIL-STD-1553B, redundant buses are employed.

LAN topology usually encompasses bus couplers (coupling transformers with fault-isolation resistors), terminators and cabling via twinax cables (twisted shielded pair), and concentric twinax connectors (with a center contact and an intermediate cylindrical contact).

What’s the advantage of couplers?

Couplers play an important role in the overall system. Basically, they help reduce reflections and maintain signal impedence levels, resulting in the sort of mission-critical reliability that’s demanded from the system. Without couplers, there’d be no DC isolation or common mode rejection, and a simple shorting fault between the device’s internal isolation resistors and the main bus would lead to a failure of the entire bus.

Part of this function has to do with the bus coupler’s transformers, but there are also built-in fault isolation resistors designed to protect the main bus during a short circuit in the stub.

So what does MilesTek provide?

And at MilesTek, we offer the industry’s most complete line of MIL-STD 1553B data bus products, including:

1. Box-style couplers — From one-stub couplers to eight-stub couplers, and everything in between.

2. Inline couplers — From one-stub inline couplers to four-stub inline couplers—these are used in vehicles where light weight and small size are important.

3. Bus coupler kits — Integrated kits that include bus couplers, terminators, and cable assemblies.
