12F MPO-MPO patch cord is a factory-terminated MPO fiber trunk cable designed for high-density optical backbone connections between MPO modules, patch panels, and active equipment in data centers and telecom networks.
Product Overview
The 12F MPO-MPO patch cord from Spring Optical is a high-density MPO patch cable / MPO trunk cable engineered for structured fiber optic cabling systems that require compact installation, low insertion loss, and scalable network expansion.
The cable is terminated with precision MPO connectors on both ends and uses a 3.0 mm LSZH jacket, making it suitable for indoor installations where fire safety and cable management are important.
It supports:
10G Ethernet
40G Ethernet
100G Ethernet
Typical applications include:
MPO cassette interconnection
Patch panel backbone links
Ruggedized MPO fan-out systems
Data center spine networks
Telecom optical distribution systems
With modular MPO architecture, the backbone cable remains in place while only the cassette module needs replacement when connector styles change, reducing downtime and upgrade cost.
