Hytrel is a trademark of Dupont.
Laser-welded fiber alignment assembly
for long-term power stability.
The resulting characteristics are high efficiency,
excellent thermal stability, moderate threshold
current, and bandwidth greater than 1GHz. The
module includes; a photodiode for monitoring
the laser chip output power, a thermistor for
monitoring the laser submount tempertature,
and a Peltier-effect thermoelectric cooler. The
cooler can be used to maintain a constant laser
temperature or to temperature tune the spectral
frequency of the laser. Proven module design
and a rigorous quality assurance program
ensure the reliability and long operational life of
these products.
The SCW 1550 Series lasers have a nominal
wavelength of 1550nm. The light output is
coupled into a singlemode optical fiber with a
core diameter of 9um and a cladding diameter
of 125um. The fiber has a protective tight buffer
upjacket of 900um diameter Hytrel .
These lasers are typically used in short and
intermediate distance telecommunications
systems including protocols such as SONET,
SDH, and PDH. They are also used in long
distance, high-speed data communications
network applications such as "fast" Ethernet or
Fiberchannel. The SCW 1550 is an excellent
device for use in high-stability test equipment
products.
