FLEX-Link, FLEX-C, FLEX4, FLEX-Base – 1, 2 or 4 Pair UTP/STP

Overview

The FLEX series of adapters and extenders are designed to extend PoE far beyond standard Ethernet reach. When used with the FLEX24 Switch or the FLEX-Base Extender, the FLEX adapters can deliver 10/100Mbps (symmetrical, full duplex) and PoE (up to 50W) over 1- (needs local power), 2-, or 4-pair UTP/STP with up to 2,000ft (610m) reach. This helps eliminate the costs and disruptions associated with IDF closet requirements. There are three adapter options that provide deployment flexibility:

  • FLEX-Link is IEEE-compliant and negotiates power requirements with an IP device, delivers 50W of power over 4-pairs, and can be locally powered.
  • FLEX-C supports IEEE-compliant devices with lower power requirements.
  • FLEX4 is IEEE-compliant and negotiates power requirements with up to 4 IP devices, delivers 30W of power over 2-pairs, and can be locally powered
