FTTH Technology Overview
The Calix network provides any combination of voice, video and data services for Fiber-To-
The-Home (FTTH) networks. Signals are distributed from a central office and driven by
active, powered transmitters over a fiber optic network (split up to 32 ways) to the subscriber
premises without any powered signal amplification. Return signals are passively combined
using optical components, without the use of powered signal amplification. The system
architecture will support a 32-way passive split up to a distance of 6 miles. Distances between
6 and 11 miles are supported with a 16-way split and distances of 11 to 12.4 miles are
supported via an 8-way split.
For reference, a block diagram of the Calix GPON Architecture is provided.
Voice Services
Voice Services are provided through the flexible architecture of the F5s DACs (Digital
Access Cross-connect) functionality. The shelf allows for Switched and Non-Switched T1
trunking through the Quad T1 modules. The Quad T1 modules are able to transport whole
or fractional T1s as necessary. The switched services adhere to the Telcordia GR-303
standard. The GR-303 capability allows for expanded line concentration to increase the line
density and still maintain industry standard blocking ratios. The Model 560 ONT receives the
signal and provides POTS (Plain Old Telephone Service) on binding posts for connection.
