Key Considerations for Computer Room Fiber Optic Fittings

• Insertion Loss (IL) and Optical Return Loss (ORL): Low dB values are essential for high-speed networks.
• Certifications: ISO 9001, IEC 60794, RoHS, REACH, and GR-326-CORE ensure quality and environmental compliance.
• Mechanical Strength: Tensile and crush resistance testing guarantees durability during installation in dense racks and conduits.
• Connector Type: Single-mode fibers are preferred for long-distance runs, while OM4/OM5 multimode fibers are cost-effective for short data center links.
• Support and Documentation: Manufacturers providing installation guides, testing equipment, and engineering support reduce the risk of network failures .
