The ECS3510-28F switch is designed to offer a cost-effective solution for FTTH,
providing downlink fiber connections to subscribers and high-bandwidth twisted-
pair uplink connections to core switches and routers at the CO.
Some basic connection configurations are described in the following pages.

ONNECTIONS
Fiber optic technology allows for longer cabling than any other media type. A
100BASE-FX single-mode fiber link from the chassis can connect to a subscriber
up to 15 km away. The CPE is installed inside a subscriber’s premises, so there
are no active outside components between the CO and the end user.
The figure below illustrates a basic switch to CPE connection.
