Cable Construction
The DDS DFP-SMDXLCLC-3 uses a duplex fiber configuration consisting of two individual single-mode fibers combined into a duplex patch cord assembly. The yellow outer jacket provides easy identification of single-mode fiber cabling.
Construction:
LC/UPC Duplex → Duplex Fiber Cable → LC/UPC Duplex
The duplex configuration supports two optical channels, making the cable suitable for applications requiring separate transmit and receive paths.
Applications
The DDS DFP-SMDXLCLC-3 is suitable for:
- Data center fiber connections
- Fiber optic patch panels
- Optical distribution frames (ODF)
- Network switches
- Fiber optic transceivers
- SFP / SFP+ / SFP28 interfaces
- Telecom networks
- LAN and WAN networks
- FTTH and FTTx infrastructure
- Fiber-to-the-building systems
- Enterprise networks
- Server rooms
- High-density fiber installations
Standards & Compliance
The patch cord is designed to comply with commonly used fiber optic cabling requirements and connector standards, including:
- IEC 61754-20 – LC connector interface
- IEC 61300 – Fiber optic connector testing
- TIA-568 – Structured cabling requirements
- RoHS compliant materials
