Why Choose OTSCABLE Indoor Fiber Optic Cable?

What is an Indoor Fiber Optic Cable?

An Indoor Fiber Optic cable is a fiber optic cable that is flexibly built and constructed with a tightly buffered group of fibers. These are designed to run for short distances only. The distances may only be from building to building or from one floor to another in an office or home fiber optic cabling system. Moreover, indoor fiber optic cables are used for backbone fiber optic installations and can be run in narrow riser or plenum spaces.

Why Use a Tight Buffered Cable for Indoor Fiber Optic Applications?

As we like you to experience solid internet streaming, optimized bandwidth and communication with maximized fire safety precautions, we use tight buffered cables for our Indoor Fiber Optic cables. The reason is that the construction of tight buffered indoor fiber optic cables are effective for retarding flames incase of fire threat as they are compliant with ANSI/UL 1666-1997.

Tight buffered cable is also easier to splice or split and install as there is no gel-filling inside the cable. Thus, with this compact feature, indoor fiber optic cables provide more room for internal backbone cabling, horizontal cabling distribution and riser installations. 

This can be very useful for busy and complex data industries where equipment rooms are filled with piles of cable racks and fiber patch cords. 

If you want to know more on how we manufacture tight buffered fiber optic cable for indoor use, check out our manufacturing process for this type of cable.

Indoor Fiber Optic Cable Construction

Indoor Fiber Optic cables are constructed with various materials. The outer jacket of the cable is built to resist corrosion and ultraviolet radiation while preventing water contamination. Also, the outer jacket is fire retardant and is made of LSZH or ROHS compliant PVC materials that do not pose environmental and health risks. 

Aside from the tight- buffer constructed optical fiber inside, the cable is also composed of the FRP, a non- metallic material for strength and the Aramid yarn used to further provide strength and resist high tension applied to the cables.

Indoor Fiber Optic Cable Manufacturing Process: How is it made for Indoor Use

Tightly-buffered Indoor Fiber Optic Cable is made similarly as the loosely-buffered fiber optic cable used for outdoor application. 

Generally, we start with obtaining a highly purified silica glass with very few impurities. Then the following steps summarizes the process in manufacturing indoor fiber optic cable.

1. Manufacturing a preform glass cylinder
2. Drawing process of the fibers
3. Extrusion of plastic over the fiber coating
4. Strengthening, sheathing and spooling

#1 Manufacturing a preform glass cylinder

The glass used in the preform is made through Modified Chemical Vapor Deposition, or MCVD. In this process, a precise mixture 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 special equipment called the drawing tower will be 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 Extrusion of plastic over the fiber coating

At this point, the fibers are made and are passed through a cabling assembly unit that comprises a buffering assembly line that applies loose or tight coating on the optical fibers. Tight buffering is made by direct extrusion of plastic over the fiber coating. The tight-buffering process function to preserve strength, absorb shock and provide additional fiber protection.

#4 Strengthening, sheathing and spooling

Afterwards, the tightly buffered fibers are applied with reinforcing PVC sheath that protects it from impact and shock.

A spool controlled by a tractor mechanism slowly pulls the created fiber and creates the spool of the fiber, but is monitored and controlled by a laser micrometer. The measurements taken by the micrometer will ensure the precision of the fiber diameter throughout its length. Typically, the fibers are pulled at a rate of 10 to 20 m/s. 

Quality Control

OTSCABLE not only assures the best quality Fiber Optic Cables are delivered into the market, but also upholds an environmental responsibility of disposing the raw materials, in-process products and end-products which can potentially harm the environment. 

OTSCABLE 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. 

OTSCABLE 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

Certifications

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. These materials are hazardous to the environment and cause pollution to landfills. Moreover, they are dangerous when exposed during manufacturing and recycling.

Underwriters Laboratories (UL) is a Nationally Recognized Testing Laboratory (NRTL) recognized by the Occupational Safety and Health Administration (OSHA). As an NRTL, UL devises, publishes, updates, and maintains minimal standards that certain types of products: magnetic components, electronics, plastics, potable water and others.
