Fiber optic communication equipment is a core component of modern communication systems. It uses optical signals to transmit data in optical fibers and has the characteristics of high bandwidth, low loss and anti-electromagnetic interference. These devices are widely used in telecommunication networks, data centers, broadband access and industrial automation.
1. Equipment classification and function
Fiber optic communication equipment covers a variety of types, each with specific functions to ensure the stability and efficiency of communication links. The following are the main categories:
Fiber optic quick connector
Fiber optic quick connector is used to achieve fast termination and connection of optical fibers without the need for fusion splicing equipment. Its structure includes ceramic ferrules and metal shells, which are suitable for on-site installation and maintenance. Application scenarios include fiber to the home (FTTH) and network expansion.
Jumper
Jumper is a pre-terminated optical fiber cable with connectors (such as SC or LC types) at both ends for connecting optical devices (such as switches and routers). Standard lengths range from 1 meter to 30 meters, supporting internal wiring in data centers.
PLC splitter
PLC (planar light waveguide) splitter is a passive optical device based on silicon-based waveguide technology for distributing input optical signals to multiple output ports. The common splitting ratio is 1:2 to 1:64, which is suitable for passive optical network (PON) systems.
Optical cable
The optical cable consists of multiple optical fiber cores, reinforcements and sheaths, providing mechanical protection and environmental isolation. According to the structure, it is divided into central tube type, layer twisted type and ribbon type, which are used for long-distance trunk transmission or outdoor deployment.
Distribution box
The distribution box is used for the distribution, management and storage of optical fibers, and contains adapter trays and fusion trays inside. It supports modular design, which is convenient for network expansion and maintenance, and is commonly found in computer rooms and optical distribution points.
Joint box
The joint box provides sealing and protection for optical fiber joints, and adopts waterproof and dustproof design. It is suitable for outdoor environments, such as underground pipelines or pole installations, to ensure the reliability of the connection point.
Terminal box
The terminal box is used for terminal processing and fixing of optical fibers, and integrates fusion units and storage areas. It is mostly used at the user end or device end to simplify the management of access points.

2. Applications and advantages
Fiber optic communication equipment plays a key role in multiple fields:
Telecommunication networks: support high-speed data transmission, such as 5G base station backhaul.
Data centers: achieve low-latency interconnection to meet cloud computing needs.
Industrial applications: for reliable communication in harsh environments, such as smart manufacturing.
Equipment advantages include high bandwidth capacity (up to Tbps level), low signal attenuation (less than 0.2 dB/km), and long-term stability (design life of more than 25 years).
3. Key application scenarios
Telecommunication backbone network and metropolitan area network: ultra-long distance, ultra-large capacity data transmission.
Fiber to the home (FTTH) / passive optical network (xPON): use splitters to achieve point-to-multipoint access.
Data center interconnect (DCI): high-speed, low-latency connection between computer rooms (extensive use of MTP/MPO high-density cabling).
5G fronthaul/midhaul/backhaul: Meet the needs of high-bandwidth, low-latency connections between base stations.
Cable TV (CATV): Radio frequency optical signal transmission.
Industrial control and automation: Reliable communication with resistance to electromagnetic interference.
Smart grid: Power communication dedicated network.
4. Equipment selection and service considerations
Standard compliance: Follow international (ITU-T, IEC), national (GB/T, YD/T) and industry standards.
Performance indicators: Strictly evaluate insertion loss, return loss, operating wavelength, temperature range, durability, etc.
Environmental adaptability: Consider the waterproof and dustproof level (IP), temperature tolerance, UV resistance, etc. of outdoor equipment.
One-stop supply and customization:
Choose suppliers with a complete product line (such as fiber optic connectors, jumpers, splitters, optical cables, distribution boxes, junction boxes, terminal boxes) to simplify procurement and compatibility management.
