Descriptions
FRL15TCWx-D86 series is full band tunable DFB laser module designed for long haul
DWDM applications with external intensity modulator.
The polarization maintaining fiber pigtail enables to directly connect a modulator without
polarization control. The polarization state of output laser beam is maintained to a
consistent orientation.
Full band thermally tunable DFB laser diode chip is integrated with an optical isolator,
thermo-electric coolers (TEC), thermistors, a power monitor photodiode, and a
wavelength monitor photodiode in a hermetically sealed 26 pin butterfly package with
same foot print as an industry standard 14 pin butterfly package.
Full band thermally tunable DFB laser diode chip consists of DFB laser array and
semiconductor optical amplifier (SOA). Each DFB laser is biased under constant
current and output power is maintained by adjusting SOA current under automatic
power control. By selecting an appropriate DFB laser and tuning the laser temperature,
FRL15TCWx-D86 series can provide any ITU channel in 35 nm tuning range.
This laser module complies with telecom requirements described in Telcordia
TM
GR-468
and is manufactured in an ISO
TM
9001 certified production line.
