Applications of Pre-terminated Fiber Optic Patch Cords

Pre-terminated fiber optic patch cords are widely used in scenarios requiring high-density, high-performance, and high-reliability fiber optic connections, such as data centers and telecommunication rooms. Their compact design philosophy allows for savings in space and improved cabling efficiency in high-density cabling environments.

1. Data Centers: Data centers are the support sites for enterprises' uninterrupted business platform operations, requiring extremely high performance of the cabling system. Pre-terminated fiber optic patch cords, through factory termination and testing, can ensure the stability and reliability of network connections, reducing the risks caused by human operation errors.

2. Telecommunication Rooms: Telecommunication rooms are the core nodes of communication networks, with equally high requirements for fiber optic connection density and performance. The high-density design of pre-terminated fiber optic patch cords can support more fiber optic connections, improving cabling efficiency in telecommunication rooms.

Buying Tips for Pre-terminated Fiber Optic Patch Cords

1. Choose the Correct Connector Type: Select the appropriate connector type based on the type of equipment port to ensure compatibility.www.adsscable.cn

2. Select Single-mode or Multimode Fiber: Choose the fiber type based on the transmission distance and bandwidth requirements. Single-mode fiber is suitable for long-distance transmission, while multimode fiber is primarily used for short-distance transmission.

3. Select the Appropriate Cable Length: Select the appropriate length of fiber optic patch cord based on the distance between connecting devices to avoid waste and unnecessary costs.

4. Pay Attention to Cable Jacket Types: Select the appropriate cable jacket type based on requirements such as fire resistance and environmental protection, such as PVC, LSZH, or OFNP.

5. Check Product Certifications and Test Reports: When purchasing, check if the product meets relevant international standards and data center requirements, and view the product's test reports to ensure reliable performance.
