Hybrid fibre-optic PoE cable can extend up to 2KMs

Telecom network equipment manufacturer LevelOne is offering Power/Fibre Hybrid Cable (PFHC) technology which can extend a network up to two kilometres from the source (transmitter) for Power over Ethernet (PoE) devices, and one kilometre for PoE-Plus devices. Using AWG 18 cable, these distances are still up to 700 metres for PoE and 450 metres for PoE-Plus devices. Power output at the one-kilometre mark is up to 50W. The applications suggested include outdoor surveillance, digital signage and communications. From a 19-inch rack-mounted chassis (POC-4002, available soon), each PFE-1001T/1101T transmitter can send power and data up to two kilometres via hybrid fibre cable, with a PFE receiver converting power to PoE at the other end. Each receiver can then be connected to a PoE-enabled Powered Device (PD). The PFE-1014R has four ports, allowing connection for up to four PDs. For an extended surveillance installation, this enables four PoE surveillance cameras to be connected to each receiver, and eight receivers each connected to its own transmitter at the central chassis, making a network of 32 cameras possible per chassis, spread out over a two-kilometre radius. The vendor also supplies 12 or 18 AWG hybrid fibre cable with optional LC Fibre Optical Termination. The full range of PFHC devices launched by LevelOne includes the PFE-1001T/1101T transmitters, the PFE-...
