Pre Terminated cabling solutions are ideally suited for data center environments where the
cable routes are well defined and where the time for deployment, ease of installation,
network reliability and manageability are paramount.
The manufacturer should also provide 100% testing in a quality-controlled environment
before the cabling is shipped out to the work-site. Make sure the pre terminated copper or
optical fiber purchased through a manufacturer uses components that have been tested
and verified by a third party to exceed TIA and IEEE standards.
When selecting pre terminated cable assemblies, be sure to use a reliable provider that can
offer services such as guaranteed cabling performance, design assistance, certified
contractor training, and the ability to support large quantities of assemblies in the required
Process For FTTH Installation
When installing fiber at an MDU (muti-dwelling unit), technicians have a few choices for the
type of cable they choose. The most important choice is whether to use field-terminated or
pre-terminated cable. Both have their strengths and weaknesses, but we find
pre-terminated cable is almost always the best choice. In this blog, we’ll discuss the pros
and cons for pre-terminated versus field-terminated cable when it comes to cost,
installation skills and excess materials.

Cost Difference Between Methods
Many network operators choose to use pre-terminated cable because it eliminates the
need for timely and expensive fusion splicing. Since fusion splicing is a complicated process
for a technician working in the field, it requires more skill. This means service providers
need to spend more time and money training technicians, while pre-terminated cable
requires minimal training and equipment. Technicians only need to learn how to run a cable
and plug it in – leading to quicker and simpler installations.
Because of the need for enhanced training for a field-termination technician, their services
are in high demand. In developed countries these professionals generally work for large
operators and are not freely available. Those that can be obtained on the open market
often charge higher rates. In many developing countries, trained splicers and joiners are in
such short supply that it is unfeasible to use them for a project of any size.
Pre-terminated Fiber cable also costs less than low-performance mechanical connectors.
The major advantage of connectorized cables is that the quality of a laboratory-terminated
connector is able to meet the highest standards of polish and geometry as well as the best
optical performance levels without the splice losses associated with field-fit connectors.
The international standard applicable to these products is IEC 61753 and all reputable
termination houses can supply fully compliant products.
Skills Needed For Installation
It takes far less time for a technician to complete an installation using a pre-terminated
cable because the cable doesn’t need to be spliced. While fusion splicing offers comparable
performance to pre-connectorized fiber, it’s time-consuming and requires specialist
equipment and experienced engineers to carry out the practice. It also offers little by way
of future-proofing since splicing fibers together is a fixed and permanent solution. It doesn’t
allow for re-patching or replacing in such scenarios as relocating customer terminals or
swapping out damaged drop cables.
Fusion splicing involves using localized heat to melt or fuse the ends of two optical fibers
together. Typically, an engineer will strip off the cable’s protective coating to get at the
fiber itself. Once the fiber has been exposed it is cleaned with isopropyl alcohol or other
suitable cleaning agent before being inserted into a device called a fusion splicer. The
device lines the fiber ends up and welds them together. With a pre-terminated solution, the
cable just needs to be routed properly through the building. This type of installation is
much easier and the likelihood of craft errors decreases.
One option technicians have to increase the flexibility of fusion splicing is to splice-on
pre-terminated pigtails. Although in principle this works, in reality those pigtails are often
sourced from the cheapest vendor. The connectors are low quality and polished in high
volumes. This method also adds further complications such as potential mismatch of fiber
types with varying refractive indexes and mode field diameters, all of which will increase
the fiber attenuation.
Dealing With Excess Cable
With fusion splicing, there is no concern over excess cable when the process is complete.
While there is almost always excess cable leftover from installations involving
pre-terminated cable, the cable can be ordered in many different lengths to help minimize
the amount of slack after installation.
The right materials make slack storage an issue of the past. Excess cable can be mitigated
by using a small push-able cable that can coil into as small a diameter as possible for
storage. The coil of excess fiber can easily fit into specialized house boxes that hold a wide
range of cable lengths. No matter the type of fiber cable, it’s always best to have a few feet
of slack in case a repair needs to be made. Storing slack with a smaller cable (like Miniflex®
with a bend radius of five times its diameter) is more manageable than a rigid or flat cable,
which can often have a minimum bend radius of 10 or 20 times its diameter.
Fusion-spliced cable has its advantages, but pre-terminated cable is almost always the
preferred method for many reasons. The most obvious ones are how quick and easy it is to
install, and the cost-savings from hiring less-experienced technicians. While pre-terminated
cable leaves you with excess length, the proper house box can mitigate excess cable in
nearly all instances.
Pre Terminated cables are the plug-and-play solution for links between switches, servers,
and patch panels in the data center. As the computing environments and business needs of
organizations differ widely, not every enterprise will find the benefits of pre-terminated
systems outweigh the investment.
Providing reliable quality, advanced testing system and favorable price, progress of FS.COM
has never stopped. We offer a variety of pre-terminated optics including the breakout
patch cable, pre-terminated trunk cable and adapter panels. Field-terminated copper and
fiber cabling and connectivity systems are generally less costly to purchase in terms of the
various components. Just to find a suitable solution system for your own network.
Fiber optic cables like SC fiber patch cable and LC to LC patch cord are also needed. If you
have any requirement of our products, please send your request to us.
