As an indispensable part of wireless communication base stations, base station patchcord carry the transmission task of RF signals between base station equipment. CPRI, DLC, and PDLC are three common types of base station patch cords, each with different characteristics and application scenarios.
CPRI base station patch cord:
CPRI (Common Radio Frequency Interface) base station patch cord defines the digital interface between Radio Frequency Equipment Control (REC) and Radio Frequency Equipment (RE) of wireless infrastructure base stations.
DLC base station patch cord:
DLC (dual core pull-out) base station patch cord is mainly used for connecting BBU (baseband processing unit) and RRU (radio frequency pull-out module) in 3G networks.
PDLC base station patch cord:
PDLC (Armored Waterproof) base station patch cord has become a standard interface for 3G, 4G, and wireless base station remote radio, fiber to antenna, and other fields.
