Pre Terminated fiber cable - A great FTTH installation solution
                     Pre Terminated fiber cable  
A great FTTH installation solution
Introduction
 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 worksite. 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 delivery window.
Process For FTTH Installation
 When installing fiber at an MDU (multi-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 jointers 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 pushable 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.
Conclusion
 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
