| Passive
Devices-In Line Fiber Depolarizer. |
This
depolarizer is specifically designed for use with broadband
sources for applications in which the level of residual
polarization is critical to the system performance. Two
standard versions of the depolarizer are available, one
designed for use with ASE, SLD and ELED sources while the
other is designed for F-P laser sources. The depolarizers
can be custom designed to meet a range of performance specifications
and can be tailored to the customers requirements. Please
contact our technical design team to discuss your specific
requirements. Our iIn house process expertise allows to
offer extremely tight control on the optical performance,
quality and reliability. These devices are designed to meet
Telcordia standards GR1209 and GR1221. |

2: This model is not available for 800, 980 or 1060nm wavelength
range
3: The model no, 1, 2 and 10 are also available in unpackaged configuration
4: Multiple devices can be package in single box, up to 9 devices
can be packaged in a single box.
5: Custom devices can be made for linewidth smaller than <0.2dB
like DFB or fiber lasers, please consult our sale team.
6: All specifications are worst case for the wavelength range selected;
actual products commonly exhibit better specification.
7: Devices are also available with integrated In Line Fiber Polarizers
8: Other OEM packages with smaller dimensions are also available,
please consult our sales team.
9: Raman laser depolarizer is specifically designed to meet the
requirements of Polarization Dependent Gain (PDG) reduction in Raman
Amplifiers, this depolarizer can be spliced directly to the laser
or to the polarization multiplexer PM fiber pigtail. A single unit
will depolarize at any of the 14XX or 15XX pump wavelengths with
operating wavelength range, 1400 to 1525nm
All
dimensions are approximate and may vary slightly.
