Description
Overview
The DDS DFP-MM4DXLCLC-1 is a high-performance Duplex OM4 Multimode Fiber Optic Patch Cord terminated with LC duplex connectors on both ends. It is designed for reliable, high-bandwidth fiber connectivity in data centers, enterprise networks, telecommunications, server rooms, and high-speed Ethernet applications.
The cable uses OM4 50/125 µm multimode optical fiber, optimized primarily for 850 nm VCSEL-based transmission and high-speed applications such as 10GbE, 40GbE, 100GbE and beyond, depending on the network architecture and transceiver specifications.
The duplex construction provides two optical fibers in a paired configuration, supporting bidirectional communication and applications requiring separate transmit and receive paths.

Cable Construction
The DFP-MM4DXLCLC-1 uses two OM4 multimode optical fibers arranged in a duplex configuration.
Construction:
OM4 50/125 µm Fiber → Buffer → Strength Member → LSZH Jacket
The duplex arrangement maintains the two fibers together for easier installation, polarity management and equipment connectivity.
Cable Characteristics
- Violet OM4 multimode fiber
- Duplex 2-fiber construction
- Flexible design for rack and cabinet installations
- LSZH outer jacket
- Suitable for high-density environments
- A/B polarity identification
- Designed for repeated patching and normal data-center handling
Transmission Distance
OM4 multimode fiber is optimized for short- and medium-distance high-speed data transmission.
Typical maximum reach depends on the transceiver, transmission protocol, optical budget and network design.
| Application | Typical OM4 Reach* |
|---|---|
| 1GbE | Up to 550 m |
| 10GbE | Up to 400–550 m |
| 40GbE | Up to 150 m |
| 100GbE | Up to 150 m |
| 200/400GbE | Application dependent |
*Actual transmission distance depends on the optical transceiver, equipment specifications, link budget, connector losses and the selected transmission standard.
