4 POE + Fiber CCTV Systems


A PoE Switch converts the fiber to copper, and sends DC power to the PD over the UTP cabling. On the Right side of the following illustration, an Ethernet switch with RJ-45 ports resides in a server room or security office. The UTP cabling is converted to fiber using a standard media converter. The fiber is run a long distance to an PoE +Fiber Switch located near a convenient AC or DC power source, where it converts the fiber back to UTP cabling. The PoE Switch also injects PoE (DC power) over the UTP cable. At the other end of the UTP cable is an IP surveillance camera, located up to 100 meters away from the PoE Switch.

Power your remote locations over ethernet and take advantage of all the benefits of fiber including longer distances, larger bandwidth, and immunity to EMI/RFI. You can power your IP Camera using this technology. Yes, this technology will also work for your wireless LAN access points too.

  • There are several solutions available to extend the distances of PoE network links, including LAN extenders that convert Ethernet to DSL, UTP to coax converters and wireless technology. Fiber optic cabling provides several advantages over these technologies.
  • Fiber extends network distances up to 20 Kilometers per link with no data deterioration over distance like copper cabling. LAN extenders can only extend network distances about 3,300 feet, but a data rate of 100 Mbps can drop by 70% at longer distances.
  • Fiber cabling provides security benefits as well. It is a secure medium that generates no electro-magnetic emission and is very difficult to tap. Fiber is also very reliable because it is not susceptible to electrical interference, or data loss due to temperature or atmospheric conditions.
