ACT 20 meter Multimode 50/125 OM4 polarity B fiber patch cable with MTP female connectors

The ACT 20 meter Multimode 50/125 OM4 Polarity B fiber patch cable with MTP female connectors is designed for high-density network environments and short- to medium-range data transmission. With a 50 µm core and OM4 graded-index multimode fiber, the cable supports elevated bandwidth and reduced modal dispersion for applications in data centers, server rooms, and enterprise backbone links. The Polarity B configuration provides a defined fiber mapping that simplifies patching and preserves signal integrity when connecting transceivers and patch panels.

Advantages

This multimode OM4 cable offers a balance of high bandwidth and compatibility with standard multimode transceivers. The MTP female connector enables dense, multi-fiber connections while maintaining low insertion loss and return loss when properly installed. Polarity B wiring reduces the need for additional rework in racks and helps maintain consistent signal paths across parallel optics links. The 20 meter length gives flexibility for routing between equipment in larger racks or across adjacent rooms.

Suitable for

• Data center interconnects and switch-to-switch links
• High-bandwidth short-reach applications using multimode transceivers
• Parallel optics deployments and MPO/MTP trunking
• Server room cabling and rack-to-rack connections

Key specifications

• Fiber type: Multimode OM4 (50/125 µm)
• Connector type: MTP female
• Polarity: B (cross-over mapping for defined transmit/receive pairs)
• Length: 20 meters
• Performance: Optimized for high bandwidth and low modal dispersion over short to medium distances

How to use

Inspect connector endfaces for cleanliness before insertion and use appropriate fiber cleaning tools if necessary. Route the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius specified by multimode fiber standards. Insert the MTP female connectors into matching male adapters or cassettes, ensuring correct orientation for Polarity B mapping. Verify link continuity and optical power levels with appropriate testing equipment after installation to confirm acceptable insertion loss and return loss.

Recommendations

Store and handle the cable in a dry, dust-free environment. Use dust caps when connectors are not mated, and avoid excessive pulling force. For best performance in high-density environments, plan cable runs to minimize crossings and strain on connector housings, and document polarity mapping in your patching records.
