OZ Optics’ DR-100 series of digital variable reflectors enables the user to generate a known level of return loss to evaluate system response. The unit allows testing the return loss sensitivity of devices such as laser diodes, transmitters, isolators and so on. By generating a precise reflection level, system performance (bit error rate, noise levels, isolator performance) can be evaluated. A built-in calibration table accurately defines intermediate degrees of reflection from 2 dB to as high as 60 dB for different wavelengths.
DR-100 digital variable reflectors are offered using either single mode (SM), multi mode (MM), or polarization maintaining (PM) fibers. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patch cords. However OZ Optics can construct devices using other PM fiber structures. OZ Optics also carries some alternative fiber types in stock, please contact AMS Technologies for availability. If necessary, OZ Optics is willing to use customer supplied fibers to build devices.
For best results, the standard versions of the DR-100 series are designed to accept angled FC/PC connectors. Other connector types are possible with lower dynamic reflectance range.
DR-100 digital variable reflectors can be controlled remotely via a USB interface. A universal AC/DC power supply is included with all units.
The DR-100 digital variable reflectors can also be provided with a custom built-in fused coupler which directs a fraction of the reflected light to a second optical connector on the unit. The user can use this signal for monitoring the reflected power or determining the influence of reflected power on his device under test. For details, please contact AMS Technologies.
