ACT 12 meter Multimode 50/125 OM4 polarity B fiber patch cable with MTP female connectors

The ACT 12 meter Multimode 50/125 OM4 fiber patch cable with MTP female connectors is a structured-cabling component engineered for high-density, high-speed network environments. With a 50 µm core and OM4 multimode specification, this 12 m cable is intended to support 40G and 100G Ethernet links with low insertion loss and stable optical performance. The cable is built to maintain signal integrity over short to medium intra-facility runs typical in data centers and enterprise backbone segments. Polarity B wiring ensures correct channel mapping in systems that use polarity-reversal cabling schemes.

Advantages

The cable’s OM4 grade multimode fiber provides increased modal bandwidth compared with lower-grade multimode fibers, allowing higher data rates and longer modal reach for parallel optics. MTP female connectors offer high-density connectivity and easy integration with MPO/MTP panels and transceivers. The 12 meter length provides flexibility for rack-to-rack or row-to-row connections without excess slack. Polarity B configuration simplifies deployment in networks that require reversed polarity for correct transmit/receive alignment.

Suitable for

• 40G and 100G Ethernet links in data centers
• High-density MPO/MTP patching panels and trunking
• Short to medium multimode backbone connections between racks and switches
• Parallel optics applications and MPO/MTP transceiver interconnects

• Polarity: B (reversed polarity wiring)
• Length: 12 meters
• Designed for: 40G/100G Ethernet and parallel optics
• Typical use: Data center and enterprise backbone cabling

How to use

Install the fiber patch cable by aligning the MTP female connector keying with the receptacle on the MPO/MTP panel or transceiver, ensuring correct orientation for Polarity B wiring. Route the cable in cable management trays or under-floor pathways avoiding tight bends and sharp edges; adhere to the specified minimum bend radius for multimode fiber. Verify end-to-end continuity and optical loss with appropriate test tools after installation to confirm that link budget and channel mapping meet system requirements.

Recommendations

Store and handle the cable in a clean, dust-free environment; keep connector end faces covered with protective caps when not in use. Clean connector ferrules before mating and perform OTDR or insertion loss testing after installation to confirm performance. Avoid exceeding the minimum bend radius and limit mechanical stress on connector assemblies to preserve long-term signal quality.
