Frequently Asked Questions

Why Choose OTSCABLE Outdoor Fiber Optic Cable

What is an Outdoor Fiber Optic Cable?

An Outdoor Fiber Optic cable is a fiber optic cable that is built with strength and reliability with a loosely-buffered group of fibers. 

These are designed to be installed for lengthy runs, extending up to miles and miles of distance. Loose tube fibers are designed for withstanding the slap of harsh environmental conditions experienced in outdoor settings.

Why Use Loose-Buffered Cables for Outdoor Fiber Optic Applications?

As there is nothing more deserving for us than solving your slow internet experience, through the years we have undertaken major transformation in optimizing your bandwidth and communication networks. 

All our outdoor fiber optic cables, whether multimode or singlemode cables, has gel-filled loose tubes. It provides the needed protection from water from rain, snow or moisture that can possibly penetrate the cable. This is especially beneficial in eliminating water migration in cables. 

Moreover, since coated fibers are floating in a gel-filled environment, outdoor cables experiences less mechanical stress and axial force. They are optimized to allow bend radiuses, so there’s not much to worry about the extremity in bending the cables. 

Our outdoor cables can be extremely helpful in supporting 10 gigabit and 40 gigabit Ethernet.

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

Outdoor Fiber Optic Cable Construction

Outdoor 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 loose buffer constructed optical fiber inside, the cable is given a gel-filling to hold the cables together. It is further 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.

Outdoor Loose Tube Fiber Optic Cable Manufacturing Process: How is it made for Outdoor Use

Outdoor Fiber Optic Cable is made similarly as the tightly-buffered fiber optic cable used for outdoor application. 

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

  1. Manufacturing a preform glass cylinder
  2. Drawing process of the fibers
  3. Gel filling and extrusion of plastic over the fiber bundle
  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 Gel filling and extrusion of plastic over the fiber bundle

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. 

The coated fibers are made to float within an abrasion resistant and large tube that is filled with gel for optical fibers. 

#4 Strengthening, sheathing and spooling

After which, the optic fiber with loosely-buffered tube is extruded with plastic sheath. The 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


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 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.
