Video Blog: Ruggedized Connectivity Solutions

June 27, 2019 at 8:00 AM

 

In harsh industrial and military settings, standard commercial connectivity components will fail causing expensive downtime and even danger to lives in some military applications.

 

To address these demanding applications, specialized cables, connectors and other connectivity products must be used to ensure network uptime and performance.

 

Ruggedized cabling and interconnects must be able to withstand conditions such as extreme temperatures, moisture, corrosive chemicals, heavy vibration and more.

 

Communication systems for use in military operations are exposed to similar harsh conditions. Many of the voice, video and data systems used by the military are mobile and designed for rapid deployment where similar temperature, extreme shock, vibration, dust and moisture environments are prevalent. Other potential hazards encountered in these applications include heavy electromagnetic interference (EMI) and radio frequency interference (RFI), which also create connectivity problems in these environments.

 

If you’re building or managing networks in harsh environments and want to know more about the products created specifically to withstand and perform in these settings, we’re here to help. We’ve created a video to explain more about L-com’s ruggedized product solutions and the applications they’re used in. Check it out here.

 

802.3bv - The Power of Plastic Optical Fiber

August 16, 2018 at 8:00 AM

 

In the realm of IEEE standards, 802.3 is bringing a lot to the table for today’s newest innovations. This standard includes several iterations that support ground breaking technology, including 802.3at and 802.3bt that support Power over Ethernet (PoE), 802.3bz that delivers 2.5 and 5 Gbps speeds over copper and now we can add 802.3bv to that list. 802.3bv was developed to support Power over Plastic Optical Fiber (POF) and it’s slated to deliver groundbreaking speed and performance.

 

First, let’s take a look at plastic optical fiber and all of its capabilities. It is a large core, step-index optical fiber capable of speeds of up to 1 Gbps. It is easy to install, cost effective, durable and is an ideal choice for networks reaching 80 meters with infrastructure that connects to switches and/or wall plates. POF will be able to meet the higher bandwidth demands of developing technology and can be used in new applications for home, industrial and automotive networks. Thus, there has been a push for the development of 802.3bv to support all of the possible POF applications.

 

The IEEE 802.3bv standard is an amendment to the 802.3 standard that allows 1000 Mb/s speeds, allowing POF to meet the increased bandwidth needs of those automotive, industrial and home network connectivity applications. 802.3bv delivers Gigabit Ethernet operation over POF and defines physical layer specs for home, industrial and auto industries. With 802.3bv, POF Ethernet networks will have the support of a robust and reliable media option. Automotive applications will have operation over a minimum of 15 meters with 4 POF connections, and distances of at least 40 meters with zero POF connections. Home and industrial applications will be able to achieve lengths of at least 50 meters with one POF connection.

 

There are three physical layer specifications in this amendment, specifically designed for the industries targeted. All use 1000BASE-H encoding over duplex POF cable and red light wavelength transmission.

 

  • ·        1000BASE-RHA – 1000 Mb/s speeds for home network and consumer applications 

 

  • ·        1000BASE-RHB – 1000 Mb/s made for industrial applications

 

  • ·        1000BASE-RHC – 1000 Mb/s rates designed for automotive applications

 

With the development of 802.3bv, yet another layer of power and possibility has been added to the realm of IEEE standards, ensuring that the world of technology has no intention of slowing down.

 

NEMA Enclosures: Best Fit Guide

July 7, 2016 at 8:00 AM

 

With so much relying on your network being fully functional, a NEMA enclosure is one of the best ways to safe-guard your valuable equipment. NEMA enclosures are ideal for wired and wireless networks to protect critical equipment from the elements, chemicals, physical contact, theft and damage. They are designed to endure all types of abuse and keep enclosed, sensitive electronics safe.

 

The National Electrical Manufacturers Association (NEMA) rates enclosures based on criteria that includes resistance to dust, moisture, water immersion and ice. The better the rating, the more the enclosure can withstand.

 

Here, we guide you through the most popular enclosure features to help find the best fit to protect your valuable equipment.


Industrial

Most enclosures are labeled as “industrial” because they are built to be rugged and protect against the elements and feature options such as heating and cooling. They are made for indoor and outdoor use in hot and cold environments.


Weatherproof

When your equipment is located outside or in an industrial setting, such as a factory or processing plant, a weatherproof NEMA enclosure provides the insurance you need. They protect against damage from environmental hazards such as water, dust, oil and corrosive chemicals like gasoline.


Non- Powered

These protective enclosures are perfect for wired and wireless communications equipment that do not require power. L-com’s non-powered enclosures feature fully gasketed lids to ensure optimal performance. Our non-powered enclosures are also available in a variety of rugged materials including Molded Fiberglass Reinforced Polyester (FRP) and VALOX 357U thermoplastic material.

 

Powered

For equipment that requires a power source, a powered NEMA enclosure will be your best bet. They share many of the same attributes as their non-powered counterparts but can be built with power outlets for various interfaces including 12V DC, 120V AC, 240V AC and POE. Some powered enclosures also include built-in lightning protection for an extra level of security.

 

Heating and Cooling

If your equipment will be exposed to cold temperatures, extreme heat or moisture, you may want a NEMA enclosure that provides cooling, heat or ventilation. For example, L-com offers an enclosure that is ideal for keeping equipment warm and functional in sub-zero temperatures as low as -30°F (-34°C). This particular model features a thermostat-controlled heating system that is powered by a Cat5 cable and is shielded by foam insulation and fiberglass.

 

NEMA enclosures provide plenty of options that can be mixed and matched to make sure your network equipment is protected. For more information on which options will be the best fit, or to have us design a custom enclosure for you, contact us today.
