MegaBit
Gear FSU6200 (OLT) is a GE-PON*1 device
that is compliant with IEEE802.3ah standard*2 and
allows Internet connection of maximum 1
Gbps. Sumitomo Electric Networks' broad
band access technologies, abundant experience,
and the cutting-edge optical device technologies
as a manufacturer of ADSL/VDSL devices
are blended in this product. |

The
GE-PON device
"MegaBit Gear FSU6200" |
|
 |
| Major features
of this product is as follows: |
|
| I. Provides
ultrawideband services of maximum 1 Gbps cheaply
regardless of the distance between the telephone
exchange and subscriber's house. |
This system allows a "shared" service,
where one fiber optics is laid near subscribers'
households and divided to connect maximum 32
subscribers, so the connection cost is considerably
reduced compared with "occupied" service
where one fiber optics connects one telephone
exchange and one subscriber.
Not like ADSL, the transfer rates do not attenuate
regardless of the distance between the telephone
exchange and subscriber's house, so an ultrawideband
service can be provided even when the distance
between the telephone exchange and subscriber's
house is longer than 20 km. In addition, Maximum
1 Gbps of ultrawideband service can be realized
at best effort when only one household is using
the service. |
|
| II. Satisfying
security |
| MegaBit Gear FSU6200 is equipped
with a terminal authentication capability so that
it can be used in public network. This capability
allows providing services customized for each subscriber.
In addition, the communication data is encrypted,
so the data is in no danger of wiretapping by other
subscribers who share the fiber optics. |
|
| III. Advanced
bandwidth control capability |
| To efficiently control the bandwidth
with low delay, the hardware DBA*3 function
is adopted. This allows high-quality provision
of the state of the art applications such as IP
telephone and movie distribution even when the
traffic is congested. |
|
| IV. Highly
reliable fiber optics is adopted |
To realize high-speed communication
in a shared access network with fiber optics, we
have improved our DFB-LD*4 to
have higher output for this system and adopted
APD*5 as the photo
acceptance unit to realize stable communication.
We continue to contribute to development of broadband services
through product development that responds to subscribers' needs. |
