TYPICAL GPON NETWORK |
GPON is specified to be a single or dual fiber system, but almost all GPON systems are single fiber like virtually all popular FTTH technologies. There is little reason to use dual fibers, although this option is indeed allowed in the standard. |
TYPICAL GPON NETWORK WITH RF OVERLAY |
The RF overlay incorporates standard and high definition video into the fiber network using the 1550nm transmitter and EDFA. For cost savings, this topology is often used over the GPON IP solution. |
