The Pknight CR091L is a professional-grade 12-port hybrid Gigabit switch designed for demanding applications in stage productions, engineering projects, and control rooms. Featuring 4× SFP fiber ports and 8× locking RJ45 Gigabit Ethernet ports, it delivers 1000 Mbps full-duplex speed on all ports for seamless, high-bandwidth networking. Built into a 19-inch 1U rackmount metal chassis, the CR091L combines durability with efficient space utilization. Its locking RJ45 connectors ensure cables stay secure during live events or touring setups, while fiber connectivity extends up to 20 km with ultra-low latencymaking it ideal for real-time data transmission without signal loss. The CR091L also supports daisy-chaining via optical ports, allowing multiple units to be linked for extended coverageup to 20 km per connectionperfect for large-scale venues and distributed network layouts. With pass-through AC power output and a wide voltage input range (AC 90240V), it integrates smoothly into professional rack systems while offering outstanding reliability and cost-effectiveness compared to leading global brands.
Ships with LC optical modules by default
Supports both MM (Multi-Mode) and SM (Single-Mode) fiber cables
Blue and yellow connectors must be paired forproper transmission
Easy to replace and swap modules
Professional locking RJ45 ports to prevent accidentadisconnection
Stable connections even in high-vibrationenvironments
Higher connection reliability compared to standardRJ45 ports
Q: What fiber modules are included with this device
A: The CR091L comes pre-installed with LC interface optical modules, ready to use out of the box with no additional purchase required.
Q: What types of fiber cables does it support?
A: It supports both MM (Multi-Mode) and SM (Single-Mode) fiber cables, allowing you to choose the type that best fits your transmission distance and bandwidth needs
Q: Why must the fiber connectors be blue and yellow alternated?
A: To ensure correct optical signal direction and reliable data transmission, the fiber jumpers should be connected with blue to yellow and yellow to blue, forming a complete transmit-and-receive channel.
Q: Is it difficult to replace the fiber modules?
A: No. Replacing fiber modules is quick and easysimply remove the old module and insert a new LC module. No tools are required, and the process takes only seconds.
