Understanding the CPRI 7.0mm DLC-DLC Armoured Patchcord
In the rapidly evolving landscape of telecommunications, ensuring reliable and high-speed connections between Base Band Units (BBU) and Remote Radio Heads (RRU) is paramount. This is where the CPRI 7.0mm DLC-DLC Armoured Patchcord comes into play. Designed specifically for the Common Public Radio Interface (CPRI) applications, this fiber optic breakout patch cable is engineered for durability, exceptional performance, and seamless integration in outdoor and demanding environments. Whether you are deploying for 4G LTE, 5G NR, or legacy 2G/3G networks, this cable provides the ultra-low loss connectivity essential for maintaining signal integrity and network uptime.

Optical Performance Breakdown
The CPRI patch cord excels in transmission quality. The LC connectors are pre-terminated with ultra-precise end-face geometry, ensuring that insertion loss remains exceptionally low even after repeated matings. For UPC polished connectors, the return loss exceeds 50 dB, while APC versions deliver a superb ≥60 dB, minimizing back reflections that could degrade signal integrity in high-frequency CPRI links.
Outstanding Features of the CPRI Armoured Patchcord
This cable is not just another patch cord; it is engineered for the rigors of outdoor, industrial, and telecom tower environments.
– Robust Armoured Construction: The 7.0mm cable features a protective layer that resists crushing, moisture, and UV radiation, making it ideal for outdoor pathways, trays, and direct burial scenarios.
– Ultra-Low Insertion Loss: The ≤0.12 dB typical loss ensures maximum power delivery between BBU and RRU, supporting higher data rates and longer transmission distances.
– Superior Return Loss: With APC polishing, the cable offers exceptional return loss characteristics, crucial for CPRI’s high-frequency signal clarity.
– Small Bending Radius: The bend-insensitive G.657A2 fiber allows tight routing without signal degradation, simplifying installation in cramped spaces like tower cabinets.
– Environmental Resilience: Operating from -40°C to +75°C, the cable performs reliably in extreme climates. The LSZH jacket option adds safety in enclosed areas by reducing toxic smoke emission.
– Future-Proof Compatibility: Fully supports 2G, 3G, 4G, and 5G NR waveforms, ensuring your network infrastructure remains scalable.
Primary Applications for the DLC-DLC Breakout Cable
The CPRI cable is purpose-built for cellular and wireless backhaul applications.
– FTTA Deployments: Connects fiber distribution boxes directly to remote radio heads (RRH) at the top of cell towers.
– BBU-RRU Interconnection: Links central baseband units with radio units, both indoors and outdoors.
– Small Cell and DAS Systems: Provides reliable connectivity for distributed antenna systems and indoor coverage solutions.
– Cloud RAN and Centralized RAN: Used in distributed network architectures where fiber is required between processing and radio units.
– Multi-Purpose Outdoor Patch Cords: Suitable for any outdoor fiber optic patching requiring rugged, waterproof, and UV-resistant cabling.
