## Summary description

The ACT 10 meter Multimode 50/125 OM4 polarity B fiber patch cable features high-performance MPO/MTP connectors, ensuring reliable data transmission. With a core diameter of 50 µm, this cable is designed for high-speed networks, supporting bandwidths up to 40/100 Gbps. Its durable construction and flexibility make it ideal for data centers and enterprise applications, providing excellent signal integrity and minimal loss.

## Long description

The ACT 10m Multimode 50/125 OM4 Polarity B fiber patch cable is a factory-terminated link designed for high-speed network environments. Equipped with MPO/MTP connectors and a 50 µm core, this 10 meter cable supports parallel optics and short-reach multimode applications up to 40/100 Gbps. Its OM4 grading delivers improved modal bandwidth for reliable transmission in data center and enterprise backbone installations while maintaining low insertion loss and consistent polarity B wiring for multi-lane systems.
Advantages
This fiber patch cable combines OM4 multimode performance with MPO/MTP connectorization to enable dense, high-bandwidth links in limited rack space. The 10 m length offers flexibility for inter-rack and cross-connect runs without additional splices. Polarity B configuration simplifies connectivity for many parallel transceiver layouts, and the cable’s construction aims to reduce attenuation and preserve signal integrity across typical short-reach distances.
Suitable for
 Data center spine-to-leaf and top-of-rack high-density connections
 Parallel optics links for 40 Gbps and 100 Gbps transceivers
 Cross-connects and patching in enterprise backbone and telecom rooms
 Short-reach multimode fiber links within server rooms and equipment racks
Key specifications
 Fiber type: Multimode 50/125 µm
 OM grade: OM4 (enhanced modal bandwidth)
 Connector type: MPO/MTP on both ends
 Polarity: B (reversed pairwise mapping for parallel lanes)
 Length: 10 meters
 Supported data rates: up to 40/100 Gbps in typical multimode parallel deployments
 Typical use: short-reach, high-density applications
How to use
Install the ACT 10m multimode OM4 patch cable between compatible MPO/MTP ports on transceivers, patch panels, or cassettes, ensuring the connectors are clean and free of dust before mating. Verify the polarity B orientation matches the transceiver and patch panel wiring scheme to maintain correct lane mapping. Route the cable with gentle bends and secure it to avoid sharp kinks; follow standard fiber bend radius guidelines. After installation, perform insertion loss and continuity checks if required by site commissioning procedures.
Usage recommendations
Store and handle the cable in a clean environment and use a fiber cleaning tool on MPO/MTP endfaces before each connection. Avoid exceeding recommended bend radii and protect the cable from compression or crushing when deployed in cable trays or rack spaces. For consistent performance with parallel optics, confirm transceiver compatibility with OM4 multimode fiber and polarity B wiring.
