GJBFJV 8-core indoor branch optical cable: efficient, flexible, and reliable

In the information age, fiber optic communication, as the core carrier of data transmission, has put forward higher requirements for network stability, transmission efficiency, and deployment flexibility. GJBFJV 8-core indoor branch fiber optic cable (hereinafter referred to as “GJBFJV fiber optic cable”) has become an ideal choice in the field of indoor fiber optic cabling due to its innovative design concept, excellent physical performance, and wide range of application scenarios. This article will comprehensively analyze the core advantages of the product from five dimensions: structural design, material characteristics, performance advantages, installation and maintenance, and applicable scenarios.

Structural optimization: layered design, flexible and efficient

GJBFJV optical cable adopts the classic layered structure of “central reinforcement component+fiber unit+sheath”, and has been optimized according to the characteristics of indoor environment:

1. 8-core fiber unit: Equipped with 8 single-mode or multi-mode fibers (customizable according to user needs), the fiber core is made of high-purity quartz material, with a transmission loss as low as 0.36dB/km (single-mode @ 1310nm), supporting high-speed and large bandwidth data transmission requirements.
2. Non metallic center reinforcement: FRP (glass fiber reinforced plastic) is used as the center reinforcement component, which combines high strength and lightweight characteristics, with a tensile strength of ≥ 1000N, while avoiding electromagnetic interference and ensuring pure signal transmission.
3. Branch structure design: The main cable of the optical cable is integrated with the branch unit, and the branch points can be flexibly customized according to actual needs. It supports multi node access, reduces the number of fusion splices, simplifies the wiring process, and is especially suitable for complex indoor network architectures with multiple terminals.

Material characteristics: safe and environmentally friendly, durable and long-lasting

1. Flame retardant sheath material: The outer sheath is made of low smoke halogen-free (LSZH) material, which meets international flame retardant standards (such as IEC 60332-1). When exposed to fire, it has less smoke and low toxicity, effectively ensuring the safety of enclosed spaces such as computer rooms and office buildings.
2. Weather resistance and compression resistance: The sheath has excellent temperature resistance (-20 ℃~+70 ℃) and can adapt to indoor temperature differences; The compressive strength should be ≥ 3000N/10cm to avoid damage to the fiber core caused by compression.
3. Environmental certification: The product complies with environmental directives such as RoHS and REACH, does not contain heavy metals and harmful substances, and meets the requirements of green building and sustainable development.

Performance advantages: stable transmission, efficient carrying

1. Low loss and high bandwidth: Adopting precision fiber coating technology to ensure stable optical signal transmission, supporting high bandwidth application scenarios such as 10G/40G/100G Ethernet and 5G backhaul.
2. Anti interference capability: The all dielectric structure (non-metallic reinforcement+non-metallic sheath) completely eliminates electromagnetic interference (EMI) and radio frequency interference (RFI), making it suitable for highly sensitive environments such as data centers and medical equipment.
3. Excellent mechanical performance: Through multiple mechanical performance tests such as stretching, bending, and twisting (in compliance with YD/T 1258.4 standards), the minimum bending radius is ≤ 10 times the cable diameter (static)/20 times the cable diameter (dynamic), suitable for wiring needs in narrow spaces

Installation and maintenance: convenient and efficient, cost saving

1. Plug and play design: Pre installed connection heads for branch optical cables (optional interfaces such as SC, LC, FC, etc.) reduce on-site welding processes and increase deployment efficiency by more than 50%.
2. Lightweight and flexible: Small cable diameter (typical value ≤ 6mm), light weight (≤ 20kg/km), low resistance when passing through pipes and cable trays; High flexibility design supports multi angle bending, reducing construction difficulty.
3. Modular expansion: The branch structure supports “on-demand expansion”, and when adding terminals in the later stage, only reserved branch points need to be connected, without the need to replace cables as a whole, greatly reducing expansion costs.

Applicable scenarios: Wide coverage, precise matching

GJBFJV 8-core indoor branch optical cable, with its characteristics, can efficiently serve the following scenarios:
Intelligent Building: Provides FTTD (Fiber to Desktop) solutions for backbone fiber optic cables to floors and branches to rooms for office buildings, hotels, campuses, and more.
Data center: The server cluster in the computer room is interconnected, with wiring for cold and hot channels, supporting high-density and low latency data exchange.
Industrial Internet of Things: Factory workshop equipment networking, control signal transmission, anti-interference ability to ensure industrial environment stability.
Security monitoring: high-definition camera feedback, intelligent analysis system link construction, to meet the real-time transmission needs of high traffic videos.
Medical and Education: Operating room image transmission, remote teaching system, ensuring zero interruption of critical business.

Summary: The cornerstone choice for future communication

The GJBFJV 8-core indoor branch optical cable achieves a perfect balance of performance, safety, and economy through structural innovation and material upgrades. Its flexible branch design, excellent transmission performance and convenient deployment mode can not only meet the high standard requirements of the current indoor network, but also provide a reliable infrastructure guarantee for the landing of future technologies such as 5G, AIoT, edge computing, etc. Whether it is a new project or an old network renovation, choosing GJBFJV optical cable means choosing an efficient, stable, and future oriented communication transmission solution.
