What are the differences between the 30/60 and 150/300 Mb OFDM BH Power over Ethernet?
The 30/60 Mbps is 100Base-T; the 150/300 is 1000Base-T. The 30/60 Mb BH is powered via two pairs of the Ethernet drop cable; the primary power is supplied on Pin 8 (Pin 7 return) while supplementary power for the longer cable runs is supplied on Pin 5 (Pin 4 Return). The supplementary pair is also used for ODU signaling. The 150/300 Mb BH is powered via four data pairs of the Ethernet drop cable.
