OM4105/OM4106 112 G
Coherent Lightwave Signal Analyzer™/Pro™
Key Features [download PDF version]
- Complete coherent signal analysis system for polarization-multiplexed QPSK, differential BPSK/QPSK, and other advanced modulation formats
- Displays constellation diagrams, phase eye diagrams, Q-factor, Poincaré sphere, signal waveform, and extracted laser phase characteristics, with available analysis options (e.g. bit error rate)
- Optametra Signal Analysis Suite tolerates > 1 MHz instantaneous signal laser linewidth—compatible with standard network tunable sources
- OM3105 Coherent Modulation Receiver (CMR™) includes Signal and Reference tunable laser sources
- No laser phase or frequency locking required
- Smart polarization separation follows signal
- Incorporates Optametra OM3105 Coherent Modulation Receiver (CMR™) for high stability, linear, polarization-diverse, optical field detection
- Runs with Tektronix, Agilent and LeCroy real-time oscilloscopes1
- OM4106 CLSA Pro™ provides access to internal functions via its MATLAB interface
Optametra’s OM4105/OM4106 112 G Coherent Lightwave Signal Analyzers™ (CLSA™)/Pro™ are new 1550 nm (C- and L-band) fiber optic test systems for visualization and measurement of complex-modulated signals, offering a complete solution to testing both coherent and direct-detected transmission systems. Optametra’s hardware includes the OM3105 polarization-diverse Coherent Modulation Receiver™ (CMR™) enabling simultaneous measurement of any modulation format, including dual-polarization (DP) QPSK. Optametra’s software performs all calibration and processing functions to enable real-time burst-mode constellation diagram display, eye-diagram display, Poincaré sphere, and bit-error detection. Bit rates up to and exceeding 112 Gb/s (100G DP-QPSK) can be analyzed.
