Type 1 and Type 2 TeleLite Ethernet Configurations
An Ethernet configuration requires two cards; usually a Power Over Ethernet (POE) and Power
Serving Ethernet (PSE), however the same TeleLite Ethernet card can be used at each end of the
fiber span between the CFJ (Copper Fiber Junction) and Optical Electrical Interface depending on
local power arrangements, Network Ethernet Edge Devices and the terminating Ethernet modems.
2.1
Type 1a and Type 1b, General
In a
Type 1a
configuration, the TeleLite Ethernet card at the Central Office (C.O.) as the CFJ
(Copper Fiber Junction) and interfaces with the network Edge Devices, providing the Ethernet
service.
In a
Type 1b
configuration, the TeleLite Ethernet card as the CFJ (Copper Fiber Junction) is
located at the 300v Point of the GPR contour of the electric supply location and interfaces with the
network Edge Devices, providing the Ethernet service. See Figures 1 & 2.
