eR-S1110 Ethernet Repeater and Rate Converter: 2 x 10/100/1000Base-T (RJ45) ports. Auto-sensing and rate converting. Extend existing Ethernet cable length by 100m (300ft). 802.3af Power over Ethernet (PoE) compliant PD. AC power adapter included. The eR-S1110 Ethernet Repeater extends network distances an additional 100m / 328ft over 4-wire twisted pair (CAT5/6/7). You can also perform rate conversion between 10/100/1000 Mbps network links. The eR-S1110 Repeater can also operate as a Powered Device (PD) under IEEE 802.3af supporting end-span and mid-span power sources (PSE). This makes it ideal for organizations that need to deploy equipment in locations that are difficult or too costly to have separate AC power installed such as ceilings, walls and kiosks.
