Includes optical isolator
Modulation speeds up to 4Gbps
The DFB-1310-4x-50SMF-XX are designed to meet the challenges of high speed
data and telecommunications applications over distances up to 30km over
single mode optical fiber. In addition, these lasers are ideal for analog
applications such as CATV and other video networks. The lasers are mounted
inside a metal coaxial package which is then pigtailed with a 50cm singlemode
fiber and terminated with a fiber connector. The pigtail comes with a choice of
either FC or SC connectors with an APC or UPC polish. The TOSA package
includes a single stage optical isolator to minimize sensitivity to optical back
reflections.

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.

ADVANCED OPTICAL COMPONENTS
Finisar’s ADVANCED OPTICAL COMPONENTS division was
formed through strategic acquisition of key optical compon-
ent suppliers. The company has led the industry in high
volume Vertical Cavity Surface Emitting Laser (VCSEL) and
associated detector technology since 1996. VCSELs have
become the primary laser source for optical data communi-
cation, and are rapidly expanding into a wide variety of sensor
applications. VCSELs’ superior reliability, low drive current,
high coupled power, narrow and circularly symmetric beam
and versatile packaging options (including arrays) are enabling
solutions not possible with other optical technologies.
ADVANCED OPTICAL COMPONENTS is also a key supplier of
Fabrey-Perot (FP) and Distributed Feedback (DFB) Lasers, and
