The Fast Ethernet Switch is an Ethernet Fiber Switch which is specially designed for network monitoring. It has 2 x 10/100Mbps Ethernet ports and 6 x 155Mbps fiber ports. It adopts RTL8309N chips to low power consumption and high stability. It extends the transmission distance of a network from 100m to 120km via copper cables. It can extend the transmission distance; there are also many other advantages such as isolation protection, good data security, working stability and easy maintenance. Main Features: 1.Support the switch between 10/100Base-TX and 100Base-FX. 2.6 x 155Mbps full-duplex fiber ports and 2 x 100M Ethernet ports with auto-negotiation function. 3.Support 100M speed rate, /MDIX and half/full-duplex with auto-negotiation function 4.Each port has the complete LED Indicator light. 5.Support single mode single fiber,single mode dual fiber ,multi-mode dual fiber and SFP slot. 6.Support IEEE802.1d Spanning Tree 7.Support high performance function on each port. 8.Support 12V voltage input 9.Support IEEE 802.3x flow control and back pressure control. 10.Require no configuration and will instantly operate as soon as you power it up. 11.Low power consumption chip with heat sink built in to longtime efficient operation Standards IEEE802.3 10Base- IEEE802.3u 100Base-TX/FX IEEE802.3z 1000Base-/LX IEEE802.3x Flow control IEEE802.1p IEEE802.1d Spanning Tree Ethernet Port Connector: RJ45 Data Rate:10/100M or 10/100/1000M Distance: 100m UTP Type: UTP-5E or higher level Fiber Port Connector: SC/FC/ST/SFP slot Data Rate: 155M or 1.25Gbps Optical Wavelength: 1310nm/1550nm Distance: 550m~120km Performance Processing Type: Store and Forward Table Size:4K/6K/8K Buffer Space: 500kbs/1Mbit/2Mbit Jumbo Packet: 1518 bytes Back bandwidth: 3.8G/5.6G/7.2G Time Delay: Less than 150s Transmissin Distance Twisted Pair: 100m (CAT5e, CAT6 cables) Single-mode: 20km MTBF 100, 000 hours Environment Storage Temperature: -40~70 Operating Temperature: -10~55 Relative Humidity: 5-90% ( no condensation) Mechanical Structures Dimension: 215x107x26mm color: blue Material: PC+metal Due to different product batches, the appearance may be different, which does not affect use.
