I-020X-X Ont Hardware Block - Alcatel-Lucent 7302 Information Manual

The GPON connection performs a GPON transmission convergence (TC) layer
function. The GPON signal from the P-OLT terminates at a diplexer. The diplexer is
an optical module that performs optical and electrical conversion. The diplexer
interfaces with the GPON MAC on the SoC. Figure
diplexer, four POTS, and two Ethernet ports.
ONT SoC technology serves as the main hardware block for these ONTs; see
Figure 22-5.
ONT SoC technology consists of five key elements:
•
GPON MAC
The GPON MAC element on the SoC provides the GPON interface to the TC
layer via the optical diplexer or triplexer (if using RF video). This interface
supports the FSAN standards compliant GEM mode transport and provides AES,
FEC, and data fragmentation functionality over the GPON as described in
G.984.3 (GPON TC Layer) ITU specification.
