Frequently Asked Questions
What is an OM4 multimode fiber optic patch cable used for?
OM4 multimode fiber optic patch cables are used to connect network equipment in data centers, server rooms, and enterprise networks. They support high-speed Ethernet connections up to 10 Gbps and provide a cost-effective upgrade path for future 40-Gbps and 100-Gbps applications when paired with appropriate transceivers and light sources.
Why is OFNP plenum rating important?
OFNP (Optical Fiber Non-Conductive Plenum) rating indicates the cable meets strict fire safety codes required for installation in plenum spaces—air-handling areas above drop ceilings and in HVAC systems. This certification ensures the cable won't release toxic fumes if exposed to fire, making it compliant with building codes and safe for occupied facilities.
Can this 492-foot fiber patch cable support 40-Gbps speeds?
Yes, this OM4 50/125 multimode cable supports 40-Gbps Ethernet when used with appropriate 850-nm VCSEL transceivers and network equipment. The extended 492-foot length maintains signal integrity for long-distance runs, making it ideal for large data centers and campus network installations.
What are the advantages of LC-to-LC connectors?
LC-to-LC duplex connectors offer compact form factor, high-density port configurations, and secure snap-lock connections. They are industry-standard for modern data center equipment and provide reliable, low-loss connections ideal for mission-critical network infrastructure.
