Description
Overview
The DDS DFP-MM3DXLCLC-5 is a high-performance 5-meter Duplex Multimode Fiber Optic Patch Cord designed for reliable, high-speed optical connectivity in enterprise networks, data centers, server rooms, telecommunications environments, and structured cabling systems.
The patch cord uses 50/125 µm OM3 multimode fiber with LC Duplex connectors on both ends and an aqua-colored duplex cable jacket. It is suitable for connecting switches, patch panels, SFP/SFP+ transceivers, media converters, servers, and other multimode optical networking equipment.
OM3 LC-LC duplex patch cords are widely used for high-speed applications including 10 Gigabit Ethernet, while also supporting suitable 40G/100G multimode applications when used with compatible transceivers and network architecture. Comparable commercial OM3 LC-LC 3 m assemblies use the same 50/125 µm, duplex, aqua construction.

OM3 fiber is commonly used with 850 nm VCSEL-based optical transceivers for high-speed Ethernet and data-center connectivity. Commercial OM3 patch cords are specified for applications such as 10GbE, Fibre Channel and SFP+ connectivity.
Connector Specifications
LC Duplex – LC Duplex
The DFP-MM3DXLCLC-5 is terminated with LC Duplex connectors at both ends.
Connector characteristics:
- LC compact-form-factor connector
- Duplex configuration
- 1.25 mm ceramic ferrule
- Precision alignment
- Push-pull/latching mechanism
- Factory terminated
- Suitable for high-density patching
- Designed for multimode optical equipment
The compact LC connector makes the cable particularly suitable for high-density data-center racks and network cabinets.
Optical Performance
Insertion Loss
Target maximum insertion loss:
≤ 0.30 dB
Low insertion loss helps preserve the optical power budget of the connected network. Commercial OM3 LC assemblies commonly specify maximum insertion loss values around 0.2–0.3 dB depending on connector construction and testing criteria.
Return Loss
Typical PC multimode connector performance:
≥ 20 dB
Actual optical performance should be verified using the individual factory test report where required.
Cable Construction
The DDS patch cord uses a duplex zipcord configuration, consisting of two individual optical fibers joined together to form a convenient duplex assembly.
Construction Benefits
- Easy routing
- Flexible installation
- Convenient Tx/Rx identification
- Suitable for patch-panel applications
- High-density rack compatibility
- Reduced cable-management complexity
Comparable OM3 LC-LC duplex assemblies commonly use a 2.0 mm individual fiber diameter and duplex zipcord construction.
Performance & Applications
The DDS DFP-MM3DXLCLC-5 is suitable for:
- 10 Gigabit Ethernet
- Gigabit Ethernet
- Fiber Channel

10 Gigabit Ethernet
OM3 multimode fiber is particularly well suited to 10GbE short-distance network deployments.
The DDS DFP-MM3DXLCLC-1 can be used as the patching connection between compatible 10G SFP+ SR transceivers and fiber infrastructure.
The overall link distance is determined by the complete optical channel, including the permanent link, patch panels, connectors, transceivers, and other components—not by the 3 m patch cord alone.
