FAQs About Fiber Cable Wholesale

HOC has been wholesaling fiber optic cable for 19 years and we have encountered all kinds of problems, here are the most important concerns of our customers before closing the deal.

Cable Manufacturing Video Cover

Any benefits for fiber cable wholesale from China?

In a word, China has a much better industry chain. There may be wholesalers of fiber optic cable in US, UK and India, but HOC can guarantee that our prices and our service can be far exceeds your expectations.

How long does it usually take for me to receive the cable?

Depends on whether you want customize your fiber optic cable or not, and also the speed of customs clearance and logistics, but we can guarantee to ship regular standard fiber optic cable in less than 2 weeks, and we have customers in Singapore who received the goods in less than 2 weeks.

Can I come to China for Factory inspection?

Of course, but it is better to wait until the epidemic subsides. Now we support using ZOOM for online factory inspection.

What are the payment options?

You can use Western Union, which has a lower fee, or PayPal if you can accept a slightly higher fee, but please note that for new customers, we only accept the 30% T/T of the payment, or if you have been with us for years and run into cash flow pressure, we do offer OA credit.

Tight Buffer Fiber Optic Cable FAQs – The Ultimate Buying Guide

What is Tight Buffer Fiber Optic Cable?

The single-mode or multimode optical fiber with tightly covered secondary structure is called tight buffer fiber or tightly wrapped optical fiber, which is made of plastic (PVC / PVDF / LSZH / Hytrel) directly on the primary cover (UV optical fiber) of bare optical fiber.

The outer diameter of tight buffer fiber is usually 0.6mm and 0.9mm. They are the basic components of various indoor optical cables or tight buffer fiber optic cable. It can also be used alone, the secondary coated with various materials can be directly used as pigtail for the connection of various optical active or passive devices, instrumentation and terminal equipment, etc.

What’s The Tight Buffer Fiber Cable Looks Like?

For different application and laying, the tight buffer fiber optic cable may look different. But it all consists of tight buffer fiber, protection reinforcement and cable sheath.

The simplest structure is the simplex fiber optic cable, it only has a layer of aramid yarn and a PVC/LSZH sheath outside the tight buffer fiber core.

When a tight buffer fiber is designed for harsh environment, there is necessary to prepare the optical fiber with enough protection. Such as this armored tactical fiber cable, it has a spiral steel hose, aramid yarn and cable sheath with special treatment.

How Can Tight Buffer Fiber Has Great Performance?

The performance of tight buffer fiber cable comes from its cable design, materials quality, production quality, and the laying techniques.

Tight buffer fiber optic cable has a soft, easy to peel performance, while the high-performance tight buffer can be a good protection of the primary-coated fiber. With small bending radius, excellent mechanical and environmental performance, the tight buffer fiber cable can meet various requirements of the market and users.

Cable Design

Despite the good performance of tight buffer fiber, a perfect fiber cable design should also consider different conditions in its actual site, such as durability, installation, applications in the network and other site conditions.


The raw materials and production all affect the final quality and performance of a fiber optic cable. So a trustworthy brand or manufacturer is very important.

They will solve you all the problem of materials comparison with reliable quality inspection and experienced and advanced production technology.

Laying Techniques

In order to have the tight buffer fiber optic cable in perfect condition and performance, a suitable and protective laying is the basic requirement for the indoor optical network construction.

The cable bending radius, protection measures for the cable outer sheath, correct fusion splicing and effective fiber cable management are important when comes to fiber optic cable used within buildings.

What are the Applications of Tight Buffer Fiber Optic Cable?

fiber patch cable interconnect between equipment

Tight buffer fiber optic cable is generally used in indoor as patch cord, pigtail, connection between equipment, and multiple purpose distribution between floors.

It can also be used in harsh environment or outdoors, such as tactical fiber cable in military communication network.

What are the Advantages of Tight Buffer Fiber Optic Cable?

Compared with the traditional laying of fiber optic cable, tight buffer fiber optic cable is generally installed indoors. So it has several advantages to meet the high standard or indoor requirements.

Easy Stripe for Using

Unlike most optical fibers all put toghter in a loose tube, tight buffer fiber is a separate unit for each optical fiber. So the installation and management of a tight buffer fiber cable is way much easier.

Flame Retardant Performance

The secondary clading provide great protection for optical fibers inside. And because most tight buffer fiber optic cables are used indoors, it requires LSZH or cable sheath with more strict fire rating.

Tensile Properties

Aramid yarn in the tight buffer fiber has special properties such as low density, very high tensile modulus, high breaking strength and low elongation at break.

Therefore, the aramid yarn reinforcing element gives all tight buffer fiber optic cable excellent tensile properties.

What are the Types of Fiber Optic Cable?

fiber optic cable supply wholesale - hoc

According different aspect of fiber optic cable, there are many types of fiber optic cables.

Optical Fiber

Due to different transmission mode of an optical fiber, there are single mode fiber optic cable and multimode fiber optic cable.

Cable Core

How the fiber optic cable is structured is also an important specification of a fiber cable. There are tight buffer fiber cable, loose tube fiber cable, uni-tube fiber cable (or central loose tube), MLT (multi loose tube) fiber cable.

Installation Mode

Different application of a fiber optic cable has different requirements on the cable installation and laying. For instance, there are overhead/aerial fiber optic cable, duct fiber optic cable, direct burial fiber optic cable and underwater fiber optic cable.


Where a fiber optic cable is used affect its specifications too. At a larger scale, we can divide them into the outdoor fiber optic cable type and indoor fiber optic cable type.

Armored Type

For different application and specs to meet, the fiber optic cable armoring also varies. From light armored aluminum tape fiber optic cable, corrugated steel tape armored fiber optic cable, steel wire armored fiber optic cable, and heavy armored fiber optic cable with both steel tape and steel wires.

Besides all mentioned above, some industries and network system has specific type of fiber optic cable, such as mining fiber optic cable, FTTH fiber cable, power line fiber optic cable and so on.

What are the Materials for Tight Buffer Fiber Optic Cable?

breakout tight buffer fiber cable structure and materials design

This tight buffer fiber cable for breakout distribution has 6 tight buffer fiber in each 6 subunit with aramid yarn inside, and a central strength member made of FRP. Outside, all subunits are protected by a layer of water-blocking material and a cable jacket.

For construction with more requirement of optical fibers and application, there are also tight buffer fiber with various protective structure such as steel armored protection and outer sheath with extra protection.
