(FTTH)
Fiber-To-The-Home (FTTH) has always been an attractive option for Internet
access. It has all the benefits of optical fiber. It provides a future-proof network,
in that you do not have to go through the hassles of upgrading from ADSL to
XDSL, or digital co-ax to digital wireless. It does not have to struggle with
electromagnetic interference problems, and with no active “outside-plant”
components, it offers the highest reliability. Moreover, it does not require electric
power and is immune to lightning and other transients. These properties of fiber
lead to the lowest possible power and operational costs, such as maintenance,
provisioning and facilities planning.
The ECS3510-28F and CPE provide an ideal FTTH system, allowing a service
provider to extend an Ethernet connection over optical fiber directly to a
subscriber. The ECS3510-28F contains 24 100BASE-FX full-duplex single-fiber
single-mode cable connections that run from the service provider’s central office
(CO) directly to CPEs installed at subscriber premises. Each single-mode fiber
connection can be run up to a distance of 15 km from the CO. The switch also
provides four 1000BASE-T/SFP uplink ports for connections to other switches or
routers at the CO.
The CPE is typically a single-channel fiber-to-copper converter housed in a
compact unit. The CPE connects to the fiber cable from the CO and provides one
standard 10/100BASE-TX RJ-45 Ethernet port for connecting to a subscriber’s
PC, switch, or other network device using twisted-pair cable.
