Our Best-Selling Product of 2017

January 4, 2018 at 8:00 AM

 

To start off this year, we would like to take a moment to present the award for the best-selling product of 2017.  With so many high-performing, quality products in the running, the competition was fierce. But after all the votes (sales) were tallied, there was one clear winner.

 

And the winner is……(drumroll).…. the ECF504-SC5E coupler!

 

If you’re not familiar with this year’s best-selling product, here is what you’ve been missing:

 

The ECF504-SC5E is a Cat5e, RJ45, shielded, 8x8, panel-mount-style coupler that is ideal for telecom, LAN, voice/data and IDF/MDF applications. It is a part of L-com's ECF panel-mount RJ45 coupler line that combines an innovative design with a competitive price. With a solid, die-cast, metal mounting frame, these unique RJ45 couplers allow panel mounting with virtually any panel thickness.

 

This unique coupler is very versatile and was used in a wide variety of applications and purchased by a varied group of customers including OEM’s who used the ECF504-SC5E in enclosure and panel products, IT professionals and network installers who used the ECF504-SC5E in data center applications, and a host of other customers who used the ECF504-SC5E in a variety of Ethernet cable pass through applications.

 

On behalf of the ECF504-SC5E, we would like to thank all the customers who helped this product win the 2017 best seller award. Without your support, and purchases, none of this would be possible. (cue music).

 

Ethernet Switch Showdown: Commercial vs. Industrial

August 10, 2017 at 8:00 AM

 

An Ethernet switch is a great way to create a Local Area Network (LAN) to share resources. Ethernet switch LANs can allow an entire office to share the use of printers, servers, Internet connections and other Internet Protocol (IP)-based applications.

 

For decades, Ethernet switches were limited to climate-controlled IT closets and buildings for use in commercial and office networks. In recent years, their use has expanded to include Ethernet-based industrial IP networks for manufacturing, automation and process industries.

 

Here, we’ll look at the major features of commercial and industrial switches and how they differ from one another.

 

Commercial Ethernet Switches:

  • •   Designed for desk or rack mounting in controlled environments such as IT closets        and data centers
  • •   110V-240V AC powered
  • •   Limited operating temperature range, typically between 50° F to 95°F
  • •   Cannot withstand shock and vibration
  • •   Single Point of Failure (SPOF): many commercial grade switches depend on               cooling fans and other components that can compromise the entire switch if they         fail 
  • •   Most have lower Mean Time Between Failure (MTBF) than industrial switches

 

Industrial Ethernet Switches:   

  • •  Designed for harsh environments with extreme temperatures, vibration, dust and        moisture
  • •  Typically used in manufacturing facilities, mining, oil production, power plants,            waste water treatment plants and other extreme environments
  • •  Usually do not have any moving parts, such as fans (SPOF)
  • •  Conformal coating used in damp environments to cover PCB and protect                    components
  • •  Wide operating temperature range, typically from -40° F to 167°F
  • •  DIN rail mounting and small form factor allows switches to take up minimal space
  • •  Safety Extra-Low Voltage (SELV): accepting 24 V DC power makes industrial switches safer than higher powered switches
  • •  Many have an Ingress protection (IP) rating which allows the switches to resist dirt, dust and wash down
 

White Paper: Layer 3 Routing at the Network Edge

July 13, 2017 at 8:00 AM

 

Implementing Layer 3 at the edge of a LAN can have many benefits including increased network security, greater availability and improved network utilization, but it’s not always clear where Layer 3 routing should be used in the LAN. Traditionally, Layer 3 routers were at the core of the networks and acted as gateways to the Wide Area Network. As technology, pricing and availability have changed, Layer 3 routing has moved closer to the edge of the network. 

 

Our white paper discusses when to employ a Layer 3 switch at the edge of a network and gives definitions and applications for several widely used routing protocols including RIP, DVMRP, PIM and OSPF.

 

Topics covered in our Layer 3 white paper include:

 

Layer 2 Switching vs. Layer 3 Routing

 

Defining Layer 3 Routing Protocols

    -      Routing Information Protocol (RIP)

    -      Open Shortest Path First (OSPF)

    -      Internet Group Management Protocol (IGMP)

    -      Dstance Vector Multicast Routing Protocol (DVMRP)

    -      Protocol Independent Multicast (PIM)

    -      Virtual Router Redundancy Protocol (VRRP)

 

Layer 3 Routing Applications

    -      Assigning static IP routes to VLAN/Sublets

    -      Routing between Layer 2 VLAN

    -      Routing on high-speed uplinks to the core

    -      IP multicast routing with IGMP and DVMRP

    -      PIM-DM multicast routing in the LAN

    -      PIM-SM multicast routing protocol

    -      OSPF to route IP traffic through LAN into the core router

    -      VRRP in the LAN
