LINKOH gigabit Ethernet switch industrial unmanaged series are designed for industrial site environments. This network switch features a strong power input system with wide-ranging voltages (12~57V DC) incorporated into customer’s automation network to enhance system reliability and uptime. Users can easily understand the working status of the device through the power indicator (PWR) and port status indicator (Link). Both dIN-rail and wall-mount are available.
SFP Design for Flexible Distance Extension
The additional mini-GBIC slots supports SFP auto-detection and dual speed as it features 100BASE-FX and 1000BASE-SX/LX SFP fiber-optic modules, 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.
Environmentally-hardened Design
With the IP40 aluminum industrial case, the industrial Ethernet 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.
ESD Protection
The industrial unmanaged switch series provides ±6KV contact/ ±8KV air ESD protection. It also supports ±6KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.
Application：
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 LK9012P8C4F series 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.
