1400nm to 1520nm
Description
The Optilock™ VR 14xxnm Fiber Bragg Grating
stabilized Raman pump laser is used in long
wavelength, high power applications.
Patented chip materials enable the Optilock™
VR to offer excellent power stability and high
chip efficiency, as well as state-of-the-art
thermal impedance. The superior Gibraltar II
package, which operates up to 75 degrees C,
offers increased reliability and improved
thermal performance. Wavelengths from 1400
to 1520 can be specified.
Applications
The Optilock™ VR is designed to operate in
Raman amplified DWDM systems, enabling
extended system reach and span length, as
well as faster bit rates. The relatively shor ter
wavelength Raman power transfers energy to
the longer wavelength optical signal. Multiple
pumps may be used to flatten and/or broaden
gain. Superb power and wavelength locking
capability serve to ensure the long-term
reliability of Raman amplifiers.
