Fiber-optic patch cord is a fiber-optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box.
Basic Construction of a Fiber Optic Patch Cord
A fiber optic patch cord is constructed with a core, cladding, coating, strengthening fibers and cable jacket. The purity and transparency of the optic fiber inside the fiber optic tube permits the transmission of the optical signal over long distances with negligible signal loss. The strengthening protective yarn is made of Aramid. The outer cable sheath acts as a protection of the optical fibers against impact, physical damage and outside forces.
Fiber Optic Patch Cord Manufacturing Process
The first phase of fiber optic patch cord manufacturing process is by making the fiber optic cable. After which, patch cords are terminated at both ends.
Phase 1. Making the Fiber Optic Cable
Optic fibers are pure optical glass that does not contain impurities. These are the fundamental material in making the core and cladding.
The steps in making fiber optic cable can be summarized as follows:
Manufacturing a preform glass cylinder
Drawing process of the fibers
Coating Process
#1 Preform glass cylinder
We make glass by Modified Chemical Vapor Deposition, or MCVD. In this process, an exact amount of Germanium Chloride (GeCl4), Silicon Chloride (SiCl4), and many other chemicals is bubbled with oxygen. The mixture will dictate the physical and chemical properties of the glass to be formed.
The mixture is then placed inside a quartz tube or synthetic silica which are cleaned in hydrofluoric acid. This glass tube is spun in a lathe while being heated with a torch outside the tube.
The heat will result in chemical reactions, forming Silicon dioxide and germanium dioxide. Both of them will be deposited and fused inside the glass tube. This is the preform glass cylinder which will be drawn into fibers.
#2 Drawing Process of the Fibers
A drawing tower is used to produce the fibers. The preform is loaded vertically in the tower, while the preform tip is exposed by a furnace. The heat, which ranges from 1,900 to 2,200 degrees Celsius, melts the preform until it falls down through gravity. As it drops slowly, it cools down and forms the thread-like fiber.
#3 Coating Process
After the fibers are made, they pass through several coating cups and an ultraviolet light curing ovens. This process coats the fiber with multi-layers of plastics that function to preserve strength, absorb shock and provide additional fiber protection.
Thus, Phase 1 process of manufacturing a Fiber Optic Cable is concluded. Let’s proceed with Phase 2.
At this stage, we terminate the ends of the length of the fiber cable. Termination can be in two ways: with connectors that can create a joint with another fiber optic patch cord or with splices that can stand as a permanent joint between two fiber optic cables.
Different Types of Fiber Optic Patch Cord Terminations
The following fiber connector types, such as LC/SC/MTP/MPO/ST fiber optic connectors, require an adapter panel when connecting. Fiber cables with these optical connector types are usually used in data centers, telecom rooms, enterprise networks and so on.
LC Connector
A Lucent Connector (LC), as one SFF (small form factor) connector, possesses a 1.25 mm ferrule. The small footprint design gives these fiber optic connectors huge popularity in datacoms and makes them more ideal for high-density applications. Many tend to move to high-efficiency cabling with LC fiber connectors nowadays. LC fiber optic connector is considered the most commonly-used connector at present.
SC Connector
SC fiber connector was the first connector chosen for the TIA-568 standard and is a snap-in connector that latches with a simple push-pull motion. "SC" stands for "Square Connector" due to the "square-shaped" connector body. It adopts a 2.5mm ferrule, which is twice the size of the previous LC connector. SC fiber optic connector is ideally suited for datacoms and telecom applications including point to point and passive optical networking. Due to its excellent performance, fiber optic SC connector remains the second most common connector for polarization maintaining applications.
MTP/MPO Fiber Connector
Unlike the previous two fiber optic conneceors, the MTP/MPO fiber connector is a multi-fiber connector and larger than other connectors, which combines fibers from 12 to 24 fibers in a single rectangular ferrule. It's often used in 40G and 100G high-bandwidth optical parallel connections. The MTP/MPO fiber connectors are complicated due to the key-up and key-down, male and female issues. You can refer to our white paper Understanding Polarity in MTP/MPO System to have a better understanding.
ST Connector
ST (Straight Tip) fiber optic connector was created and licensed by AT&T shortly after the arrival of the FC type. The ST optic connector holds the fiber with a ceramic, spring-loaded 2.5mm ferrule that stays in place with a half-twist bayonet mount. They are usually used in both long and short distance applications such as campuses and building multimode fiber applications, corporate network environments, as well as military applications.
FC Connector "FC" refers to the Ferrule Connector. FC fiber optic connector was the first optical fiber connector to use a ceramic ferrule. Unlike the plastic-bodied SC and LC connector, it utilizes a round screw-type fitment made from nickel-plated or stainless steel. The FC fiber optic connector end face relies on an alignment key for correct insertion and is then tightened into the adaptor/jack using a threaded collet. Despite the additional complexity both in manufacturing and installation, the FC connectors still provide the choice in precision instruments such as OTDRs, as well as the choice for single mode fiber. It was initially intended for datacoms and telecoms applications but was used less since the introduction of the SC and LC fiber optic connectors. The usage of both ST and FC connectors have declined in recent years.
The abovementioned five fiber optic connectors are the most commonly used ones, which are introduced based on their popularities from wide to usual. The figure below shows the different connector style:
Dierite not only assures the best quality Fiber Optic Cables are delivered into the market, but also upholds an environmental responsibility of disposing raw materials, in-process products and end-products which can potentially harm the environment.
Dierite follows a round of quality checks throughout the production process from raw material acceptance to production and to end-products processing prior to shipping.
Raw-Material Quality Control (RMQC)
High-quality raw material is paramount in delivering standard-wise end-products. Upon delivery of the raw materials, they go through inspection that determines whether they pass or fail. Failure to meet specific standards will automatically reject the raw materials.
Production Quality Control (PQC) Mass producing fiber optic cables from the raw materials stored in the warehouse is carried out in the production area.
Dierite also carries out a series of quality checks in the production area whether daily, weekly, monthly or yearly. This is to check if certain measures should be done in their machines or manufacturing process should be improved or fixed to meet safety standards for both the process and their employees.
In-Process Quality Control (IPQC) and Unfinished Product Quality Control (uPQC)
These are checks that are carried out during mass production is completed. In-process materials would be strictly tested for identity, quality, strength and purity as appropriate and approved or rejected by the quality control unit during the production process.
Quality Control Before Packing and Final Quality Control
Before the spooled fiber optic cables are packed or boxed, the QC unit checks the products for the following:
Tensile strength of the fiber
Attenuation
Bandwidth
Numerical aperture
Cut-off wavelength
Mode field diameter
Chromatic dispersion
The following physical checks are also performed for both multimode and single-mode fibers:
Cladding circularity/eccentricity
Cladding diameter
Coating outer diameter
Coating outer non-circularity
Coating concentricity error
Core-clad concentricity error
Core non-circularity
Core diameter
Certificates
CE Approved Products with a CE marking indicates conformity with safety, health and environmental protection standards for products sold within the European Economic Area (EEA), however, this is also recognizable worldwide.
RoHs RoHS stands for Restriction of Hazardous Substances. A RoHS listed product means the product has passed qualifications preventing the use of banned hazardous materials electrical and electronic products.
