Fiber optic communications and power network
A fiber optic-based communications network includes: a power insertion device, connected to multiple fiber links from a data source, configured to provide power insertion to a hybrid fiber/power cable connected to at least one fiber link of the multiple fiber links; the hybrid fiber/power cable, connecting the power insertion device to a connection interface device, configured to transmit data and power from the power insertion device to the connection interface device; and the connection interface device, configured to provide an interface for connection to an end device via a power over Ethernet (PoE)-compatible connection and to provide optical to electrical media conversion for data transmitted from the power insertion device to an end device via the hybrid fiber/power cable and the PoE-compatible connection.
1. A fiber optic-based communications network, comprising:
a power insertion device, connected to one or more fiber links from a data source, configured to provide power insertion to one or more hybrid fiber/power cables connected to the one or more fiber links;
the one or more hybrid fiber/power cables, connecting the power insertion device to one or more connection interface devices, wherein each hybrid fiber/power cable is configured to transmit data and power from the power insertion device to a connection interface device; and
the one or more connection interface devices, wherein at least one connection interface device is configured to provide an interface for connection to an end device via a power over Ethernet (PoE)-compatible connection and to provide optical to electrical media conversion for data transmitted from the power insertion device to the end device via a hybrid fiber/power cable and the PoE-compatible connection.
2. The network of claim 1 , wherein the data source is a networked data center comprising a patch panel, wherein a network switch is connected to the power insertion device via the patch panel and the one or more fiber links.
3. The network of claim 2 , wherein the networked data center further comprises a media converter array (MCA), configured to provide electrical to optical media conversion for data transmitted from the network switch to the patch panel.
4. The network of claim 2 , wherein the power insertion device is located at a distance of approximately 30 m or less from the one or more connection interface devices, and wherein the power insertion device is located at a distance of approximately 300 m or more from the networked data center.
5. The network of claim 1 , wherein the one or more connection interface devices comprise a plurality of connection interface devices connected to the power insertion device via respective hybrid fiber/power cables and connected to respective end devices.
6. The network of claim 5 , wherein at least one end device connected to a connection interface device is provisioned for a different data transmission rate than another end device connected to another connection interface device.
7. The network of claim 5 , wherein at least one connection interface device has a non-PoE Ethernet connection to an end device.
8. The network of claim 1 , wherein the PoE-compatible connection utilizes: a PoE protocol, a PoE+ protocol, an LTPoE++ protocol, and/or a PoE3+ protocol.
9. The network of claim 1 , wherein the power insertion device comprises a power supply, the power supply being configured to draw power from a mains power connection.
10. The network of claim 1 , wherein at least one connection interface device is configured to operate in a PoE-active mode under conditions where the end device is a non-Powered Device (PD) end device, and to operate in a PoE-passive mode under conditions where the end device is a PD end device.
11. The network of claim 1 , wherein at least one hybrid fiber/power cable includes copper wires for power transmission having a gauge of 18 American wire gauge (AWG), 22 AWG, or 24 AWG.
12. The network of claim 1 , wherein the power insertion device is configured to provide up to 180-watt power via a hybrid fiber/power cable and a connection interface device to an end device.
