SpeedyCables OM4 LC-to-LC Fiber Patch Cable 75m Magenta LSZH Duplex for 10G–100G Data Centers

SpeedyCables OM4 LC-to-LC 75m multimode patch cable is a magenta LSZH duplex fiber cord engineered to deliver reliable 10G–100G connectivity for data centers and high-bandwidth networks.

Built from 50/125µm OM4 multimode fiber and finished with Low Smoke Zero Halogen (LSZH) jacketing, this 75-meter (246 ft) LC–LC patch cable balances long-reach performance with safety and flexibility. It supports modern transceivers and delivers low insertion loss and high return loss for stable links across server rooms, telecom closets, and campus backbone runs.

How fast and far will this OM4 LC-LC cable carry signals?

This OM4 multimode fiber is optimized for high-bandwidth Ethernet and short-range data center links. It sustains high modal bandwidth and supports typical multimode distances for modern speeds while keeping signal loss low.

• 10GbE: up to about 400 meters
• 40GbE: up to about 350 meters
• 100GbE: up to about 125 meters
• Modal bandwidth: ~4700 MHz·km @850nm for robust performance

Will this cable fit my hardware and transceivers?

The SpeedyCables OM4 cable terminates in factory-polished LC connectors, a common duplex form factor for SFP+, QSFP+, and many multimode transceivers. Connector quality and ceramic ferrules help maintain predictable link characteristics when paired with compatible optics.

• Connector type: LC-to-LC duplex (push-pull latching)
• Compatible with SFP+, QSFP+, SR and multimode transceivers
• Insertion loss: typically ≤0.3 dB per connector
• Return loss: ≥30 dB for clean signal reflections

Is this cable durable and safe for indoor installations?

The cable uses an LSZH jacket to reduce toxic smoke and corrosive gases in the event of fire, making it suitable for enclosed spaces and regulated environments. Its construction also prioritizes bend tolerance and mechanical handling for rack-mounted and tray installations.

• Jacket: LSZH (low smoke, zero halogen) – safer for indoor use
• Color: magenta OM4 identification for quick visual sorting
• Bend radius: 7.5 mm minimum to maintain performance
• Rugged ferrules and precise polishing for longevity

How easy is it to install and manage in high-density racks?

Designed for tidy routing and straightforward terminations, the duplex LC footprint helps conserve panel space while keeping polarity consistent. The cable’s flexibility and standardized connectors reduce installation time in dense cabling environments.

• Duplex LC format for compact port density and clear polarity
• Flexible jacket for routing through cable managers and trays
• Precise connector ferrules minimize rework and testing time
• Available in multiple lengths to match rack-to-rack distances

Who is this for: Network engineers, data center operators, system integrators, and IT teams that need reliable multimode fiber links for high-throughput, short-to-medium-distance connections. If you’re deploying or upgrading 10G/40G/100G infrastructure and prioritize safety, predictable optical performance, and easy installation, this SpeedyCables OM4 LC–LC patch cable is a practical choice.
