Pre-Terminated Cabling System—An Ideal Solution for Data Centers

Posted on by

When designing and implementing their high-density networks, most data center managers and operators are inclined to options which are more sustainable and environmentally sound. They always expect systems to provide high performance and reliability for maximum network uptime over the long term. Since the demand for higher bandwidth and flexibility for future growth never ending, network administrators now are seeking to the network’s physical media infrastructure to achieve these goals. And the growing adoption of pre-terminated cabling system serves as one of the trend, that is what we will explain in this article.

What Is Pre-Terminated Cabling?

Then what the pre-terminated cabling system refers to and how it differs from field terminated one? In fact, pre-terminated cables go through the same procedures as field terminated cables, but these steps are taken at the manufacturer’s facility or cable assembly house and delivered to the job site with the connectors already terminated, properly polished, and the entire cable assembly tested on either both or one end. Which helps to eliminate the necessity for on-site field termination. Compared with field terminated cabling products, pre-terminated fiber cable assemblies are more convenient and flexible. They are most suited for network installations that are planned well in advance, taking into account both current and future requirements.

What Pre-Terminated Cabling System Can Achieve?

Installing and connecting your cable infrastructure in the data center consists of various labor intensive tasks. And manual field terminations, troubleshooting, and error corrections also extended deployment times, higher installation costs and increased downtime. However, with the deployment of pre-terminated cabling system, you are supposed to benefit from it with the following aspects:

  • Installation time and costs are substantially reduced.
  • Material reductions of 50 percent or more are typical when using pre-terminated systems rather than traditional systems.
  • Network performance and reliability are assured due to in-factory testing and validation of components.
  • Modular components at the physical layer are reusable. They can be disassembled and repurposed to accommodate moves, adds and changes, which provides greater flexibility and portability, as well as a clear migration path to support new technologies and applications as an organization grows and requirements change and evolve.
  • Pre-terminated installations are more precisely planned, which results in a neater, cleaner appearance, as well as faster and easier cable management, maintenance and troubleshooting.
Common Pre-Terminated Fiber Cables

It is undeniable that pre-terminated fiber cabling system indeed offers a constructive and ideal solution to data center management and maintenance. Here in this part, we will further introduce some most commonly employed pre-terminated fiber cables, including fiber patch cables, fiber optic pigtails and MTP/MPO pre-terminated cables.

Fiber Patch Cables

As one of the most used components in fiber optic networks, fiber patch cables help to ensure a reliable temporary fiber optic interconnection. There exists a wide range of fiber patch cables on the market, available in single-mode and multimode versions with PVC, LSZH, OFNP or armored jacket. And connection type options involve LC, FC, SC, ST, MU, MTRJ and E2000 pre-terminated in duplex or simplex fiber. Fiber patch cables are suitable for all kinds of fiber optic connectivity applications.

Fiber Optic Pigtails

Fiber optic pigtail, which is a fiber optic cable of a specified length, has only one end terminated with the appropriate connector style and an open unterminated end. A pigtail can be fusion spliced onto a pre-terminated fiber optic cable assembly to extend the cable distance or onto field-terminated cables to provide the connectorized end. Pigtails do not need the same configuration or connector style as the opposite end. Keep in mind that when installing pigtails, you must be trained and will need additional equipment, such as a fusion splicer and fusion splice trays.

MTP/MPO Pre-Terminated Cables

Pre-terminated with high-quality and low loss MTP/MPO connectors, this kind of cable can meet the high-speed, high-density, and wide bandwidth demands of the current and future network. Basically, both MTP/MPO trunk cables and MTP/MPO harness cables are classified into this category. They are available in any fiber mode (single-mode and multimode) and a full range of length options.

Conclusion

Pre-termination cabling is not just a popular trend, it is an increasingly popular way of delivering a project in a more timely and cost effective manner. Which on the whole can provide benefits for all sizes of project.

Single Mode and Multimode Fiber Optic Cable

Posted on by

In recent years fiber optic cable has become apparent that optical fibers are steadily replacing copper wire as an appropriate means of communication signal transmission. They span the long distances between local phone systems as well as providing the backbone for many network systems. Other system users include cable telecision services, university campuses, office buildings, industrial plants, and electric utility companies.

There are three types of fiber optic cable commonly used: single mode, multimode and plastic fiber optic. Although fibers can be made out of transparent plastic, glass, or a combination of the two, the fibers used in long distance telecommunications applications are always glass, because of the lower optica atenuation. Both multimode and single mode fibers are used in communications, if you need to transmit less data over longer distances, use single mode fiber optic cables. For a greater data capacity over shorter distances, go with multimode fiber optic cables, with multimode fiber used mostly for short distances (up to 500 m),Multi mode is often used for LANs and other small networks. And single-mode fiber used for longer distance links.

Single Mode Fiber: Single Path through the fiber

Single Mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Single Mode is also referred to as single-mode fiber, single-mode optical waveguide, mono-mode optical fiber and uni-mode fiber. Single-mode fiber gives you a higher rate of transmission, it also can carry the signal up to 50 times farther distance than multimode, at a slightly higher cost.Single-mode fiber has a much smaller core than multimode.

Single Mode fiber is used to connect long distance switches, central offices and SLCs (subscriber loop carriers, small switches in pedestals in subdivisions or office parks or in the basement of a larger building). Practically every telco’s network is now fiber optics except the connection to the home.

Multi Mode Fiber: Multiple Paths through the fiber

Multi-Mode cable has a little bit bigger diameter, with a common diameters in the 50-to-100 micron range for the light carry component (in the US the most common size is 62.5um).Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. Multi Mode fiber is used for shorter distances. Most applications in which Multi-mode fiber is used, 2 fibers are used. Multimode fiber gives you high bandwidth at high speeds (10 to 100MBS – Gigabit to 275m to 2km) over medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable’s core typically 850 or 1300nm. Long cable runs (Above 3000 feet 914.4 meters in length), the multiple paths of light are believed to cause signal distortion at the receiving end, resulting in lost packets and incomplete data transmission. IPS recommends the use of single mode fiber in all applications using Gigabit and higher bandwidth.

About Fiber Optic Pigtail

Posted on by

Fiber optic pigtails are recommended or sometimes required when there is a need to make a transition from thin buffered fibers (250-900um), typical for distribution cables and not suitable for direct optical fiber connector termination, to cross-connection or equipment connection point. Pigtails mechanically or fusion connected to the distribution cable fibers simplify cabling system installation and servicing significantly. Fiber optic pigtails are used to achieve accurate mounting for precision alignment of fiber optical components. The fiber pigtails are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets.

Fiber pigtail is piece of fiber optic cable with only one fiber optic connector on one side of the cable while leave the other side no connectors, so that the connector side can link to the equipment and the other side can be melted with optical fiber cables. Commonly used fiber optic pigtail types are SC, ST, FC, LC MT-RJ, SC/APC, FC/APC, E2000 fiber optic connectors. They are single mode types and multimode types.

Fiber optic pigtails the typical use is to link the fiber optic cable with fiber optic equipment, the fiber optic pigtail with connector side is used to link the equipment, while the other side of the pigtail is melted together with the fiber cable, by melting together the fiber glasses, it can reach a minimum insertion loss. Common types of fiber optic pigtails are usually with 0.9mm fiber cable diameter, and usually installed inside ODF unit. Most commonly used types are SC fiber optic pigtail, ST fiber optic pigtail,FC fiber optic pigail, LC fiber optic pigtail ,MT-RJ fiber optic pigtail,SC/APC fiber optic pigtail, FC/APC fiber optic pigtail and E2000 fiber optic pigtail.
