Optical Transceiver Lines
Optical technology enables the transmission of data, voice
and video as light waves along fiber, and allows significantly
higher speeds and greater bandwidths than conventional copper
wire. Digital information - consisting of digitized video,
voice telephony, interactive gaming, business files, spreadsheets
and www information - is prepared for delivery to a home
or business. Distribution of this high bandwidth content
is accomplished over a strand of optical fiber, either directly
from one location to another (Point-to-Point) or via optical
splitters (Point-to-Multipoint) in a Passive Optical Network
(PON).
To modulate this data onto the laser and to recover the
very weak receive signal requires a very accurate driver
and a highly sensitive amplifier. Centillium has combined
these tasks, with added functionality including monitoring
diagnostics, into a range of innovative bi-directional laser
transceiver interface products.
Centillium’s Transceiver Line:
Centillium’s
newest range of transceiver chipsets, Apollo 2 and Zeus 2,
deal with a broad spectrum of data delivery
infrastructures by offering a single footprint device that
addresses multiple applications. The results are flexibility
and savings along the entire design chain from the transceiver
and optical access equipment vendor to the service provider.
Centillium has integrated a broad range of functionality
into a small, standards-compliant package, without the need
for a separate microcontroller.
The chipsets include features such as automatic power control
(APC) which contribute to cost savings for equipment vendors
and service providers in design, manufacturing, inventory
and testing as well as ensuring long-term stability of the
laser set up. The highly accurate digital diagnostic monitoring
(DDM) capability allows service providers to have clear-cut
visibility into network operations, thereby permitting them
to maintain a tight control on the health of their networks.
Apollo 2 Product Family: Support for Point-to-Point Data
Transfer
The Apollo 2 transceiver chip enables control
of point-to-point data traffic over fiber, and targets various
areas of the
continuous data mode environment including compliant versions
for all standards and data rates from 100Mbps through OC3,
OC12, Gigabit Ethernet, and OC48 architectures. Meeting stringent
standards compliances, Apollo 2 addresses systems vendors
and service providers’ requirement to easily offer
a multitude of applications on a wide spectrum of data-delivery
modes for deployment on a global basis.
Zeus 2 Product Family: Support for Point-to-MultiPoint Data
Transfer
The Zeus 2 transceiver chip enables control of bi-directional
burst-mode traffic over fiber with versions for both CO and
CPE supporting GPON, EPON and A/BPON architectures complying
with the relevant IEEE and ITU-T specs. Zeus 2 offers a range
of integrated capabilities enabling our customers to develop
new transceiver designs for coming standards such as GPON
and at the same time, allows them to save costs in their
current architecture designs.
