DFB-1310-4X-LC
The DFB-1310-4x-LC are designed to meet the challenges of high speed data
and telecommunications applications over distances up to 20km over single
mode optical fiber. In addition, these lasers are ideal for analog applications
such as CATV and other video networks. The lasers are packaged in a
hermetically sealed TO56 package and then packaged into a metal receptacle
that is designed to meet very stringent optical wiggle requirements. The TOSA
package includes a single stage optical isolator to minimize sensitivity to
optical back reflections.
Includes optical isolator
Modulation speeds up to 4Gbps

NOTICE: Stresses greater than those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation
of the device at these or any other conditions above those
indicated in the operations section for extended periods of
time may affect reliability.
NOTICE: The inherent design of this component causes it
to be sensitive to electrostatic discharge (ESD). To prevent
ESD-induced damage and/or degradation to equipment, take
normal ESD precautions when handling this product

Notes:
1. Operating current is the average bias current required to meet the ER, rise/fall, and bandwidth specifications. The target
operating condition is 35 mA over threshold at high temperature, 30mA over threshold at RT.
2. Other output power range is possible per customer request.
3. TOSA would be capable of meeting other specifications when modulated over this ER range.
4. Maximum change in power as fiber is rotated by 360º.
5. Measured with an optical receiver with a 3.125 Gb/s filter
6. Rise and fall times are measured 20-80%
7. Resistance is measured between ITH + 10mA and ITH + 20mA
8. Tracking error is defined as the coupled power difference at Tmax or Tmin (relative to 25°C) where the back monitor current,
Imon, is held constant at the value found at 25°C at I=Iop.
