GPON Brings Triple-Play Service to Consumers
PON is data network implemented with optical fiber but no intervening electrical (active) transceivers. This lowers the cost of optical networks and makes short-range (20 to 60 km) broadband connections using fiber practical and affordable.
Already, PON is widely used in Asia and some parts of Europe. SBC and Verizon both are testing and installing PONs in selected parts of the U.S. It won't be long before triple-play services (TV, data, and Voice over Internet Protocol) can be offered over very high-speed PONs.
Asymmetric 10G EPON OLT XFP Transceiver
The prevailing PON standard in the U.S. is broadband PON (BPON), also known as ITU-T standard G.983.x. It features a maximum download data rate of 622Mbits/s. Passive optical splitters are installed in the fiber to allow up to 64 subscribers to use the line. The GPON standard ITU-T G.984 bumps the speed options to 1.244 and 2.488Gbits/s and is backwards-compatible with BPON.
Also, the GPON standard provides greater speed and a higher split ratio than the competing EPON or Ethernet PON, which maxes out at 1.25Gbits/s and a 1:32 split ratio. GPON offers a huge cost savings over EPON—not to mention the greater capacity.
