FiberGateway
2.4 General Architecture
The GPON IC Processing unit is the core component inside FiberGateway. It is responsible for the
interconnection and processing between client side interfacing and optical GPON Uplink interface.
2.4.1.1 GPON
The FiberGateway GPON layer as G.984.x uses 1490nm downstream and 1310nm upstream of the
optical wavelengh, with 2,488Gbps downstream and 1,244Gbps upstream by using an SC/APC
protected optical connector.
2.4.1.2 Ethernet
Ethernet is the wired LAN technology and is revised in the IEEE 802.3 standard. At the OSI reference
system, Ethernet is at the Data Link layer. In the FiberGateway equipment both WAN and LAN type of
physical interfaces is 10/100/1000BASE-T AUTO-MIX Ethernet type over RJ45 conectors.
2.4.1.3 IPTV
For the IPTV service the FiberGateway also behaves like a Layer 2 bridging device. For this service,
the FiberGateway has a specific GEM PORT for Multicast. This same GEM PORT is requested by the
user in order to have access to the various IPTV channels. Every time a user requests a new channel,
the FiberGateway will send to OLT a IGMP packet requesting that Channel. The FiberGateway is also
responsible for implementing the snooping for the channels that the user requests.

2.4.1.4.1 Supported interfaces
FiberGateway voice service provisioning could be made through OLT configurations over OMCI
messages or could be downloaded (FTP) from the OLT up to the FiberGateway after its registration on
