FLYPROFiber 75M OM4 LC-LC Fiber Patch Cable – Duplex MMF, 10G/40G/100G, LSZH, 75m

Overview

Meet the FLYPROFiber 75m OM4 LC-LC multimode fiber patch cable, designed for high-density networking and reliable connectivity in data centers, enterprise labs, and professional IT spaces. This duplex MMF cable brings together robust construction, precise engineering, and practical features that support a range of Ethernet speeds and transceiver types without sacrificing clarity or signal integrity.

Key capabilities

• Length: 75 meters (246 ft) to reduce the number of splices and jumpers in compact environments
• Duplex LC-to-LC connectors with LC/UPC polish for clean terminations
• Multimode fiber core 50/125 μm supports high-speed links in data centers, campuses, and premises networks
• LSZH (low smoke zero halogen) jacket provides safer cabling and safer installation in restricted spaces
• Adjustable connector clips for quick fiber access and straightforward Tx/Rx identification

Performance and reliability

Operating at 850 nm, this OM4 MMF cable supports a range of distances and speeds that are common in modern networks. Theoretical reach and bandwidth are complemented by solid, real-world attributes:

• 1 Gb Ethernet distances up to 550 meters, 10 Gb up to 300 meters, 40 Gb up to 300 meters, and 100 Gb up to 200 meters
• Bandwidth rated at 2000 MHz·km at 850 nm for robust signal transfer across longer links
• Insertion loss ≤ 0.3 dB and return loss ≥ 30 dB help preserve signal quality and reliability

Design features and installation tips

The jacket uses an environmentally friendly LSZH formulation, combining safety with durability. Precision alignment is supported by Japan-made zirconia ceramic ferrules and a UPC polish, helping maintain signal integrity across connections. Embossed A/B position labels on the duplex clip and jacket rings labeled 1 & 2 aid quick identification during installation, testing, and troubleshooting.

In tight SAN cabinets or dense data-center cabinets with numerous bends, the 7.5 mm minimum bend radius of the 50/125 μm fiber helps minimize optical loss and maintain stable transmission even when cables are routed through crowded pathways.

Real-world use cases

Ideal for connecting 40G BIDI SR, 10G SR, QSFP+ and SFP+ transceivers in high-density racks, this patch cable serves as a practical solution for data centers, enterprise campuses, and network closets where reliability and space efficiency matter. It’s a strong candidate for deployments seeking to balance performance with safety and ease of installation.
