LINKOH LK9003P1C2F Industrial Switch is an unmanaged Gigabit Ethernet Switch that features 1-Port Gigabit RJ45 + 2-Port Gigabit fiber optical port,which is equipped with an IP40-rated rugged but compact-size case for stable operation in heavy industrial demanding environments. Being able to operate under the temperature ranging from -40℃ to +75℃. It provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curbside traffic control cabinets.
3-port Switch Mode or 2-port Fiber Redundant Mode
Via a DIP switch, the two SFP fiber interfaces of LK9003P1C2F can be configured as Ethernet switch mode or fiber redundant mode. With the Ethernet switch mode, it can operate in Store-and-Forward mechanism with high performance; with the 2-port Fiber redundant mode, it provides rapid fiber redundancy of link for highly critical Ethernet applications. The redundant mode supports auto-recovering function. If the destination port of a packet is link-down, it will forward the packet to the other port of the backup pair.
SFP Design for Flexible Distance Extension
The additional mini-GBIC slots supports SFP auto-detection, meaning the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and 10/20/30/40/50/60/70/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications to uplink to backbone switch and monitoring center in long distance.
With the IP40 aluminum industrial case, the industrial gigabit switch provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets without air conditioning. It features a ventilated construction without fan, thereby making its operation noiseless. Being able to operate under the temperature range from -40 to 75 degrees C, can be placed in almost any difficult environment.
The industrial unmanaged switch series provides ±8KV contact/ ±15KV air ESD protection. It also supports ±4KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.
FTTX Solutions for MAN Application
To build a network solution of FTTX, including FTTH, FTTC and FTTB, the various distances of SFP transceivers are optional for customers. With two Gigabit-speed SFP, the deployment distance of the switch can be extended up to 120 kilometers (single-mode fiber), which provides a high-performance edge service for FTTx solutions. The LK9003P1C2F is the ideal solution for service providers such as ISPs and telecoms to build Metropolitan Area Network (MAN) based on the fiber technology.
Network Extension Deployment Solution
With its additional 2-port 1000BASE-SX/LX SFP fiber optic Ethernet link capability, the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. They are well suited for applications to uplink to backbone switch and monitoring center in long distance.
