Why to Choose Pre-terminated Copper Trunk Cable?

For data center and enterprise deployments, pre-terminated copper trunk cable is a wonderful choice to achieve simple and quick installation. It can fit most patch panel port densities and improve better airflow and cable management. With the right upfront planning and coordination, these copper trunk cables can offer major benefits over terminating twisted-pair cables in the field. This article will take you to explore the pre-terminated copper trunk cable.

 

What Is Pre-terminated Copper Trunk Cable?

Pre-terminated copper trunk cable is a kind of cable which has gone through the same procedures with other cables. But their connectors have already been terminated, properly polished, and the entire cable assembly tested on either both or one end in the factory. Copper trunk cables are typically comprised of bundles of 6, 8, or 12. Since they are bundled together, there is no need to worry about the cable mess. Pre-terminated copper trunk cables provide a quick “plug-and-play” solution for links between switches, servers, patch panels and zone distribution areas in the data center.

 

Advantages of Pre-terminated Copper Trunk Cable

Increase the speed of deployment

Compared to field terminations, pre-terminated cabling can reduce installation time by up to 75 percent.

 

Improve cable management

Pre-terminated solutions are ideal for data centers, which are designed with consistent distances between cabinets and rows.

 

Remove the need for transmission performance testing

For pre-terminated copper trunk cable, the transmission testing is performed by the manufacturer before shipment.

 

Avoid time-wasting rework

Pre-terminated copper trunk cables are terminated in the factory, and many of them are provided in a cassette format. This format allows installers to “plug and play” multiple connections with one cassette, which reduce installation time obviously.

 

Termination Types of Trunk Cable

When selecting copper trunk cables, to choose the right termination type is a very important step, which is based on the layout of the data center or telecommunications room. it’s worth noting that the accessibility of the active equipment (including servers, switches, etc.) and the proper patching solution should be considered during the process of selection. Generally, there are four common termination types: jack-to-jack, jack-to-plug, plug-to-plug, and jack-to-open. Different types have different requirements for installation. The following will introduce these four termination types respectively:

 

Jack to Jack: This termination type is typically used in cabinet-to-cabinet permanent link trunk. In general, it is installed into empty patch panels on both ends in common interconnect and cross-connect architectures. The use of patch cords is used to complete the connectivity between the active equipment and the physical layer.

 

Jack to Plug: Typically used for in-cabinet or cabinet-to-cabinet equipment cord harnesses, the jack-to-plug type is installed into the patch panels on one end and switch ports on the other end for switch port replication applications, eliminating one cross-connect point by having the cable plugged directly into the active equipment.

 

Plug to plug: Typically used to make a direct connection between active equipment, e.g. server to switch, eliminating cross-connect capabilities. It can also be used in an open-space work area as a bundled patch cord group.

 

Jack to Open: This type is similar to jack-to-jack configuration, but one end should be cut to length and field-terminated to a target termination place, such as 110-style panel, patch panel or wall plate. Field testing of the drops is necessary after the cables have been terminated in this case.

 

Deployment Considerations

1. Copper Cable Type

Copper trunk cables using Cat5, Cat5e, Cat6 and Cat7 cables are all available in the market.

 

2. Cable Count

The most commonly used copper cables usually have 6 or 12 cables in one bound. Higher or lower cable counts are also available.

 

3. Breakout Length

Breakout length refers to the dimension from the end of the braided sleeve to connectors at the end of the cables. This dimension is part of the overall length, not in addition to the length measurement. The primary consideration for breakout length is to have flexibility to route the cables as needed.

 

4.  Proper Length

For pre-terminated copper trunk cable assemblies, length is a very important parameter to be ordered which help users to achieve the best performance.

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
