Cabling in Medical Devices

September 13, 2018 at 8:00 AM

 

When we think of cabling, we usually think of data and communications and networking, but there are all types of industries and applications that use cabling. The medical field is one of those industries that is increasingly using technology in medical devices, and wiring and cabling have been a large component in the growth of those technological advancements.

 

There are many medical devices that are dependent on interconnect components such as cabling, but unlike cabling used for a communications network, the requirements for medical device cables are somewhat unique. Medical devices cables must be extremely flexible and withstand repeated flexing. They also have to meet stringent regulated safety guidelines that vary depending on what type of device the cable will be used in and how/if it will come in contact with the patient. In addition to constant flexing and safety requirements, these cables also must be able to withstand constant sterilization processes, which include autoclave, gamma and exposure to chemicals and solvents.  

 

Another challenge of medical device cabling is keeping up with devices as they get smaller. For example, MRI machines now fit into a single room, ultrasound machines are now portable on mobile carts and consumer medical devices are handheld. The miniaturization of medical devices has many benefits including increased mobility and diagnostic capabilities, lower power requirements and less distance from the patient. Plus, the miniaturization of cables in these devices results in less cabling weight which makes maneuvering the cables around the patient easier. It also allows for greater flexibility since cabling with a smaller diameter can be tightly bent and still retain the recommended minimum bend radius.

 

Some of the most important cable factors to consider when it comes to cabling in medical devices are reliability, cable jacket, mating design and connector type. When it comes to people’s health, the reliability of a cable can be the difference between life and death. If cables are working properly or the connections aren’t reliable, devices can malfunction and that can cause great harm. With that in mind, cable connectors have to be properly mated, which can be made easier with the use of color-coding or keyed connectors. Plus, cables with alternative contact designs, such as hyperboloid, are good solutions to avoid issues with contact design, and plug-and-play connectors simplify the task of connecting different pieces of equipment. Lastly, selecting the proper cable jacket, whether it needs to be flexible, insulated or able to withstand a corrosive environment is critical to the overall operation of any cable.

 

The medical industry can be a demanding environment for cabling, and there are many requirements to consider, but as this is an industry with technology that is constantly advancing, and so will the need for cables. 

 

The Mighty MPO Connector

August 30, 2018 at 8:00 AM

 

Imagine a connector that can save you time, save you space and still perform – there you have the mighty MPO connector. Multi-fiber push on (MPO) connectors have gained popularity and are the primary multiple fiber connector used globally for high-speed data and telecom communications networks. These mighty connectors come in an array of options and make life easier while delivering the fast speeds needed for today’s technology. Here, we’ll take a look at what makes the MPO connector so mighty.

 

First, let’s look at the design. MPO connectors are designed to combine many fibers in one connector, which reduces the amount of time needed for splicing and connecting fibers, and also saves space. Each connectors has a key on one side. A “key up” position has the key on top, “key down” position has the key on the bottom. Each fiber in the connector is numbered left to right (P1, P2, etc.) and there is a white dot on the connector body to show where position 1 is located.

 

Originally, MPO connectors were only offered as single-row, 12-fiber connectors, but now there are multiple variations available. Today, there are 8 and 16 single-row options that can then be stacked to create 24, 36 and 72 fiber connectors with multiple precision ferrules. Mating these connectors is made simple through the IEC 61754-7 and EIA/TIA-604-5 (FOCSI 5) standards that ensure all MPO connectors meet performance and mateability requirements. Though, keep in mind that the wider connectors and stacked ferrules are susceptible to greater insertion loss and reflection problems because holding the outer fibers alignment tolerances is challenging.

  
 

Now, let’s look at how these mighty connectors perform. As mentioned above, MPO connectors are a popular choice for high-speed telecom and data communications. They have been utilized in duplex 10 Gig fiber applications as a means to ease cable management, save money, speed-up installation and take-up less space. Twelve-fiber MPO connectors can supply six-10 Gig transmit fibers and six-10 Gig receive fibers. Eight-fiber MPOs are capable of 40 Gig speeds and 24 fibers deliver 100 Gig speeds. With connectors able to be combined and stacked to increase speed and capabilities, MPO connectors can deliver the performance specs to keep up with future increased data requirements.

 

As a diverse connector option with great flexibility and ease of use, MPO connectors are a mighty powerful and mighty fine option for many connecting needs and are sure to remain a viable option in the fiber optic marketplace for a long time to come.
