Tenda TEF1109P-8-63W 9-Port 10/100Mbps Desktop Switch With 8-Port PoE TEF1109P-8-63W has network amplification technology. Based on the original twisted pair, it can support up to 250 metres long distance transmission, breaking the hundred metres transfer limit. With 6KV lightning protection, it is the real monitoring private switch. Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. It provides a maximum PoE output power of 30W to each port and 58W across the whole device. Lead security transmission power supply to a higher level - 6KV Lightning Protection | long distance transmission - Maximum PoE Output Power 58W | PoE power up to 30W for each PoE port Up to 250 metres long distance transmission, beyond hundred metres transfer limit Due to the complex monitoring environment, when making cabling and networking, it is usual to encounter the problem of inadequate network transmission distance, the distanceof each camera terminal to the monitoring center is different, some are only a few meters, some are hundred metres, while others are more than kilometers. Tenda TEF11 series PoE monitoring switches, exclusive patent network extension technology, use the common existing twisted pair, can support 250 meters data transmission, break the transmission limit of the existing twisted pair only for one hundred meters; Providing gigabit linked SFP port, can meet the demand of transmission to a few tens of kilometers. 6KV lighting protection PoE switch is the real monitoring private switch In real monitoring project, cameras are often installed outdoor or in a higher position, which also increases the probability of lightning shock toward the cameras and PoE switches. Therefore, some of the equipments may be damaged and even the whole local area network (LAN) may be paralyzed. Tenda TEF11 series switches have professional lightning protection design 6kV port and power supply thunder prevents. These two protection design can effectively inhibit the lightning current from the network cable and power supply, which is equivalent to add a security Walls to the entire network monitoring system. And the test standards are far higher than the requirements of the state CCC. In the thunderstorms, the monitoring network can also provide stable and reliable services to the monitoring network and ensure the normal transmission of the images. Outstanding PoE Power Supply Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. It provides a maximum power supply of 30W to each port and 58W to the whole device. - 6KV lighting protection - IEEE 802.3af/at - 250m Transmission Standard & Protocol IEEE 802.3, IEEE 802.3u, IEEE 802.3x, IEEE802.3ab, IEEE 802.3af,IEEE 802.3at Indicator Link/Act, PoE Status, Power, 100M Fixed Port 8 x 10/100Base-TX RJ45 Ports(Data/Power) 1 x 10/100Base-TX RJ45 Port(Data) Lightning Protection 6KV Wire-Speed Forwarding Support Switching Capacity 1.8 Gbit/s MAC Address Table 4K MAC PoE Supply Management Port 1 to Port 8 support standard IEEE802.3at/af power( maximum power for each port is 30W) PoE power type is end-span(1245 , 3678- line pair) in full configuration PoE Max Power Supply 58W Dimension ( W x D x H ) 177.5 x 104 x 26 mm Input Voltage AC 100 240V  50/60Hz DC 51V /1.25A Power Adapter £© Environment Operating Temperature: 0 ~40  (32H~104H) Storage Temperature: -40 ~70  (-40H~158H) Operating Humidity: 10 ~90 non-condensing Storage Humidity: 5 ~90 non-condensing One-Button-Start Mode Default Mode: If Default mode is enabled, the device works as a general switch and all ports support 10/100Mbps auto-negotiation.
