4. Applications
• Data Center Interconnections (e.g., server-to-switch, switch-to-router links)
• Local Area Networks (LANs) and Metropolitan Area Networks (MANs)
• Optical Distribution Systems (ODSs) and Fiber-to-the-X (FTTx) deployments
• High-Speed Optical Communication Systems (e.g., 10G/40G/100G Ethernet, SDH/SONET)
• Telecommunication Backbone Networks and Enterprise Network Infrastructures
5. Installation Guidelines
• Prior to installation, inspect the cable and connectors for physical damage (e.g., bent fibers, cracked connectors, jacket abrasion).
• Ensure mating connectors are clean and free of dust/debris; use approved optical connector cleaning tools (e.g., lint-free wipes, cleaning sticks) to remove contaminants.
• Align the key of the MPO/MTP connector with the corresponding slot on the mating port to avoid misalignment damage.
• Insert connectors firmly but gently; do not apply excessive force (maximum insertion force ≤ 20 N).
• Maintain the specified bend radius during routing and installation to prevent fiber breakage or performance degradation.
• Avoid exposing the cable to extreme temperatures, moisture, or chemical substances during installation and operation.
• After installation, verify signal transmission performance using an optical power meter or OTDR (Optical Time-Domain Reflectometer) to ensure insertion loss and return loss meet specifications.
6. Assembly Requirements
• Fiber Termination: Fibers are precision-terminated with MPO/MTP and LC connectors using industry-standard assembly processes (e.g., epoxy curing, polishing).
• Polishing Quality: Connector end-faces are polished to UPC/APC standards, with no scratches, pits, or contamination.
• Cable Length: Customizable according to application needs (standard lengths range from 1m to 10m; longer lengths available upon request).
• Labeling: Each cable is labeled with core count, fiber type, and connector types (labeling material is oil-resistant and durable).
• Quality Control: 100% tested for insertion loss, return loss, and continuity before delivery; test reports are available upon request.
