Echipamente de comunicații cu fibră optică 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. Clasificarea și funcționarea echipamentelor
Fiber optic communication equipment covers a variety of types, each with specific functions to ensure the stability and efficiency of communication links. Următoarele sunt principalele categorii:
Conector rapid fibră optică
Conector rapid fibră optică 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.
Splitter PLC
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.
Cablu optic
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.
Cutie de distributie
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.
Cutie comună
Cutia de îmbinare oferă etanșare și protecție pentru îmbinările din fibre optice și adoptă un design rezistent la apă și praf. It is suitable for outdoor environments, such as underground pipelines or pole installations, to ensure the reliability of the connection point.
Cutie de borne
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.
Ningbo Goshining Communication Technology Co., Ltd. provides customization services, allowing equipment to be designed according to specific requirements (such as size, interface or environmental adaptability) to support branded solutions.
2. Aplicații și avantaje
Echipamentele de comunicații cu fibră optică joacă un rol cheie în mai multe domenii:
Telecommunication networks: support high-speed data transmission, such as 5G base station backhaul.
Centre de date: obțineți o interconectare cu latență scăzută pentru a satisface nevoile de cloud computing.
Aplicații industriale: pentru comunicare fiabilă în medii dure, cum ar fi producția inteligentă.
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. Scenarii cheie de aplicare
Rețea de telecomunicații și rețea de zonă metropolitană: transmisie de date la distanță ultra-lungă, cu capacitate ultra-mare.
Fiber to the home (FTTH) / passive optical network (xPON): use splitters to achieve point-to-multipoint access.
Interconectarea centrului de date (DCI): conexiune de mare viteză, cu latență scăzută între camerele computerelor (folosirea extinsă a cablurilor de înaltă densitate MTP/MPO).
5G fronthaul/midhaul/backhaul: satisface nevoile de conexiuni cu lățime de bandă mare și cu latență redusă între stațiile de bază.
Televiziune prin cablu (CATV): transmisie de semnal optic cu frecvență radio.
Industrial control and automation: Reliable communication with resistance to electromagnetic interference.
Rețea inteligentă: rețea dedicată pentru comunicarea energiei.
4. Alegerea echipamentelor și considerații privind service-ul
Conformitate cu standardele: Urmați standardele internaționale (ITU-T, IEC), naționale (GB/T, YD/T) și din industrie.
Indicatori de performanță: Evaluați cu strictețe pierderea de inserție, pierderea de retur, lungimea de undă de funcționare, intervalul de temperatură, durabilitatea etc.
Environmental adaptability: Consider the waterproof and dustproof level (IP), temperature tolerance, UV resistance, etc. of outdoor equipment.
Aprovizionare și personalizare unică:
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.
Ningbo Goshining Communication Technology Co., Ltd. provides customized services (such as special length jumpers, specific splitter ratio splitters, OEM/ODM brand customization) to meet the special needs of the project.
