Data Sheet
September 1999
1241/1243/1245-Type Uncooled Laser Transmitter
Recommended User Interfaces (continued)
1-497(C)
Note: Input can also be connected to DATA; unused input pin remains unconnected.
(622 Mbits/s and below only.)
Figure 3. dc-coupled, Single-Ended Input
1-498(C)
* This network introduces a slight offset between DATA and DATA, which turns the laser
transmitter off when there is no data present at the inputs. (622 Mbits/s and below only.)

Qualication and Reliability
To help ensure high product reliability and customer satisfaction, Lucent Technologies is committed to an intensive
quality program that starts in the design phase and proceeds through the manufacturing process. Optoelectronics
modules are qualied to Lucent Technologies internal standards using MIL-STD-883 test methods and procedures
and using sampling techniques consistent with Bellcore requirements. The 1241/1243/1245 series of transmitters
have undergone an extensive and rigorous set of qualication tests. This qualication program fully meets the
intent of Bellcore reliability practices TR-NWT-000468 and TA-NWT-000983. In addition, the design, development,
and manufacturing facility of the Optoelectronics unit at Lucent Technologies Microelectronics Group has been cer-
tied to be in full compliance with the latest ISO-9001 Quality System Standards.
