To continue meeting the high demands of instant access , businesses need to assess their network infrastructure. Slow internet speeds, high latency and “capped” connections can be the cause of losses in business productivity and efficiency. And in some of those areas is where fibre optic networks can assist.
5 Benefits to Using Pre-Terminated Fiber Optic Cables
Written by Ben Hamlitsch, trueCABLE Technical and Product Innovation Manager RCDD, FOI
While bulk fiber cable, or field-terminated fiber, is used in many installations, there are also benefits to using pre-terminated fiber optic cables. It is especially common to see pre-terminated fiber optic cables used for 40Gb and 100Gb connectivity solutions. But they are also used in 10G and simple point-to-point installations where the requirement is to connect between two buildings or a main house and a garage. These are all possible reasons to use pre-terminated fiber optic cable, especially when terminating a connector is beyond the installer's understanding or simply to make installation time much shorter. Why might pre-terminated fiber optic cables be more common, and what benefits are there in running a pre-terminated fiber optic cable? Let’s look at some of the advantages and disadvantages of both field-terminated and pre-terminated cables as we go into more detail and describe five benefits of pre-terminated fiber optic cable assemblies and what pre-terminated fiber optic cable assemblies are.
Field termination describes the termination of the fiber optic cable in the field or after installation has taken place. When these types of cables are terminated, they need to be pulled between two points, and then connectors will need to be attached and then connected to a patch panel. In addition, before they can be attached to a panel, connectors need to be attached to each individual strand, and a variety of tools will be needed.
Let’s look at some of the advantages and disadvantages of field-terminated fiber cable:
Advantages
Precision lengths: Because these cables are cut to length before adding connectors, it's not necessary to have these cables pre-determined for length.
Easy pull system: Fiber optic bulk cable is very easy to pull from either end of the installation circuit.
Disadvantages
Higher labor costs: When fiber optic cables are terminated in the field, costs can be high. There are a variety of other tools needed, many steps need to be taken, and field technicians need to have the right training.
Slower installations: Installation will take longer due to terminating connectors and making sure the fiber optic cables and assemblies are working properly with testing.
Potential termination issues: Termination issues can occur depending on the skill level of each technician and their knowledge of fiber optic cables and assemblies. Field-terminated fiber optic cable may be inexpensive at the time of purchase. However, extra expenses could be encountered in the field through termination, raising the cost of any project.
These cables are the same as fiber optic cables that are terminated in the field; the only difference is that the manufacturer will terminate these cables with all the necessary connectors prior to shipment. This allows the manufacturer to precision polish all the end faces of the fiber connectors and ensure the terminations are within the required specification. From the installer's viewpoint, this can drastically decrease installation time.

Let’s look at some of the advantages and disadvantages of pre-terminated fiber optic cable assemblies:
Advantages:
Lower costs and time savings: Since these cables arrive pre-terminated on site, there is no cable termination preparation, connectors, or tool kits. These cables require minimal time and effort for implementation for any installer, whether experienced or not.
Project efficiency: These cables are manufactured and shipped to the job site with the connectors already terminated, precision polished, and the entire cable assembly tested on both ends to verify insertion and return loss, eliminating the time it takes to terminate the connector and then test it. This allows for a much faster and easier installation.
Disadvantages:
Need for accuracy: For these cables to perform, they need to have accurate measurements. Users will generally need planned lengths and lead times in advance in order for the pre-terminated fiber optic cable to arrive on time and as planned within the timeframe, as well as to avoid unneeded and often additional work in managing extra cable lengths.
Associated costs: Miscalculations of measurements can lead to additional expenses, which could increase the material costs of a project.
Installing (1) 12-strand pre-terminated fiber optic cable assemblies or pre-terminated fiber assemblies can reduce overall installation costs by nearly 50% (or more). This is done by eliminating rework and achieving termination efficiency, whereby the pre-terminated cable is precision polished. It may also be possible to eliminate in-depth testing as the pre-terminated links have already been tested at the factory and provide insertion loss and return loss results. It can also eliminate the need for end equipment and consumables because there is no need to cleave, splice, or polish the connector. Utilizing these savings can help pre-terminated fiber installations significantly reduce the overall installation cost.
The manufacturing process has improved in speed and can provide pre-terminated fiber optic components in two to four days (they may take longer to reach the destination depending on where they are coming from). Pre-terminated fiber can be ideal for helping to shorten project deadlines and increase overall deployment speed. Without the need to wait a week, two weeks, or even three weeks to get a custom fiber optic component, this can be a real time saver when it comes to fiber deployment.
Designed for rapid deployment, pre-terminated fiber cabling requires no field termination. This reduces the labor required, so you can get the job done faster. You need to do some pre-planning, but once you receive the cable, you can start.
Mission-critical fiber networks require the highest-level performance in the cable assembly. Due to poor air quality, low-end face polishing efficiency, and poor cleaning and test protocols, field termination can affect the overall quality of the termination, which will result in higher insertion loss and poorer return loss. Pre-terminated fiber optic components are manufactured in a clean room and undergo a series of inspections, including multiple end-face inspections and certification of specific insertion loss and return loss thresholds. The cable is tested end-to-end before it reaches the job site to ensure it is a quality, high-performance cable.
In many cases, installers must contend with waste removal from the job site. In many projects, this includes cable reels. Some installers may mix their projects together, leaving a box filled with odd-length cables, and I hope there is a project to use them.
Which should I choose?
The decision ultimately depends on what you are looking for as well as the skill level of the technicians you have working on your project. Some would prefer pre-terminated fiber optic cables or assemblies since they can be faster and simpler alternatives to field-terminated cables and require less training for technicians.
When you are calculating fiber optic costs, make sure to factor in production costs such as labor, tools, and other elements needed to terminate fiber optic cable accurately. Then, decide which type of fiber optic cables and assemblies will work best for your project.
