The AL-CAT6JW lightning and surge protector provides superior lightning and surge protection with improved frequency response for indoor 10/100/1000 Ethernet networks. The use of ultra-low capacitance semiconductors provides superior high frequency response and improved return loss for the four data pairs. The unit has low line to line and line to ground capacitance to minimize distortion of high-speed signals. The design provides protection for both common and differential mode surges. The design utilizes Thyristor diode technology which has superior power handling capability compared to TVS or Zener diode based designs. In addition, the unit is compatible with 802.3af Power-over-Ethernet (PoE) devices. This device supports PoE mode A and B for power. The unit supports normal and reverse polarity PoE used in some Cisco Access Points. The AL-CAT6JW is compatible with wireless Access Points, Bridges, Client Adapters and Network Appliances with or without Power-over-Ethernet (PoE) functionality.The compact weather resistant housing features a lockable hinged cover and mounting holes are provided on the rear of the enclosure for mounting. The cable grommet may be adjusted to cable size and are removable.This protector is also available in a shielded version for indoor applications, see HGLN-CAT6JNot sure which level of protection is required for your application...
