Multi-Mode Duplex Network Patch Cord

　　The multi-mode duplex network patch cord is a short-distance, high-bandwidth solution designed for bidirectional data transmission, making it indispensable in data centers, enterprise LANs, and server rooms where symmetric send/receive capabilities are critical. Like its single-mode counterpart, it features two separate multi-mode fibers (typically 50/125um or 62.5/125um core/cladding) in one jacket—one for transmission (Tx) and one for reception (Rx)—eliminating cable redundancy and simplifying management in dense cabling environments.

　　Leveraging multi-mode fiber’s strengths, this duplex cord supports high data rates (10 Gbps, 40 Gbps, 100 Gbps) over short distances: up to 550 meters for 10 Gbps (OM4 fiber) and 100 meters for 100 Gbps (OM5 fiber). The wider 50/125um core (compared to single-mode’s 9um) allows it to work with cost-effective VCSEL transceivers, making it a budget-friendly choice for short-haul networks. The duplex design is ideal for applications requiring simultaneous data flow, such as server-to-switch connections (sending data to the switch while receiving instructions), SANs (transmitting storage data while receiving access requests), and high-definition video streaming (sending video feeds while receiving control signals).

　　Equipped with popular connectors like LC-LC or SC-SC, the duplex cord ensures compatibility with common multi-mode hardware. LC-LC duplex cords are compact, perfect for high-density data center racks where space is at a premium, while SC-SC duplex cords offer a robust, easy-to-handle design for enterprise installations. The two fibers are color-coded (e.g., aqua for Tx, gray for Rx) to prevent misconnection, a simple yet critical feature that speeds up installation and reduces errors.

　　Constructed with a durable, flexible jacket (PVC or LSZH) that resists abrasion and tangling, and tested to meet TIA/EIA-568-C.3 and IEC 61754 standards, this patch cord delivers consistent performance. Available in lengths from 0.5 meters (server-to-ToR switch) to 100 meters (data center pod connections), the multi-mode duplex patch cord balances speed, cost, and practicality for short-distance symmetric networks. For organizations needing bidirectional high-bandwidth connectivity without the expense of single-mode, it is the ideal solution.
