4 Core Advantages

Product Introduction

• COF CoaXPress Over Fiber Range Extender is a flagship CXP2.0 fiber extension solution, consisting of Device Side (CXP2_COF_4D) and Host Side (CXP2_COF_4H). It realizes bidirectional conversion between CXP electrical and optical signals, breaking the transmission distance limit of coaxial cables.
• Supports 4 independent CXP2.0 channels, adaptive rate from 1.25Gbps to 12.5Gbps, lossless low-latency transmission, ideal for high-speed industrial cameras, long-distance machine vision and industrial automation.
• Integrates PoC (Power over CoaXPress) function: the device side can power CXP cameras directly without extra wiring. Host side supports dual power input for system stability.
• Industrial-grade design, wide temperature, strong anti-interference, plug-and-play, compatible with all standard CoaXPress cameras and frame grabbers for quick system integration.
