1. The Fast Ethernet Switch is an Ethernet Fiber Switch which is specially designed for network monitoring.It has 1x10 or 100Mbps Ethernet ports and 7x155Mbps 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 2. Support the switch between 10 or 100Base-TX and 100Base-FX. 7x155Mbps full-duplex fiber ports and 1x100M Ethernet ports with auto-negotiation function. Support 100M speed rate, or MDIX and half or full-duplex with auto-negotiation function 3. Each port has the complete LED Indicator light. Support single mode single fiber,single mode dual fiber,multi-mode dual fiber and SFP slot. Support IEEE802.1d Spanning Tree 4. Support high performance function on each port. Support 5V voltage input. Support IEEE 802.3x flow control and back pressure control 5. Require no configuration and will instantly operate as soon as you power it up. Low power consumption chip with heat sink built in to longtime efficient operation Standards: IEEE802.3 10Base- IEEE802.3u 100Base-TX or FX IEEE802.3z 1000Base- or LX IEEE802.3x Flow control IEEE802.1p IEEE802.1d Spanning Tree Ethernet Port: Connector:RJ45 Data Rate:10 or 100M Distance:100m UTP Type:UTP-5E or higher level Fiber Port: Connector:SC or FC or ST or SFP slot Data Rate:155M Optical Wavelength:850nm or 1310nm or 1490nm or 1550nm Distance:550m-120km Performance: Processing Type:Store and Forward Table Size:4K or 6K or 8K Buffer Space:500kbs or 1Mbit or 2Mbit Jumbo Packet:1518 bytes Back bandwidth:3.8G or 5.6G or 7.2G Time Delay:L than 150s Power: Power type:external power supply Input Voltage:AC100V-240V 50 or 60Hz Connector:DC Socket Working Voltage:5V Power Consumption:2.2W-3.5W Transmissin Distance: Twisted Pair:100m (CAT5e, CAT6 cables) Muti-mode:2km Single-mode:3 or 20 or 40 or 60 or 80 or 100km MTBF:100,000 hours Environment: Storage Temperature:-40-70 Operating Temperature:-10-55 Relative Humidity:5-90percent ( no condensation) Due to different product batches, the appearance may be different, which does not affect use.
