Alnair Labs Launch the EYE-2000C

The Eye-CheckerTM (EYE-2000C) optical sampling oscilloscope is a low-cost alternative to the conventional optical sampling scope, which requires an external electrical clock for synchronisation.
The EYE-2000C employs an advance software algorithm, CodeSyncTM, to accomplish clock-recovery on any optical signal without the need for an external clock. The latest software included with the scope is fully native C compiled utilising OpenGL ultra-fast graphical library for real-time operation with functionalities such as eye-diagram analysis, Q-factor and BER performance prediction, to data bit pattern unravelling, sequence recognition and visualisation. Options for a second optical channel for applications requiring two synchronised optical signals, DPSK signals, optical or electrical clocking and triggering for packet, or burst signals are also available.

The Fast Dispersion Analyzer (FDA-2100J) features fast speed and high accuracy for measuring dispersion parameters of optical fiber and components. With Alnair Labs proprietary phase detection technology, the instrument can resolve group delay (GD) or differential group delay (DGD) better than 100fs. The instrument is interfaced with user friendly software which allows chromatic dispersion (CD), polarization mode dispersion (PMD), power or insertion loss (IL) and other important polarization parameters such as polarization dependent loss (PDL) and principle state of polarization (PSPs) Polarization parameters are measured based on Jones Matrix Eigen-analysis (JME).

High group delay resolution < 0.05 ps
1,000 measurement per second
Modulation phase-shift method up to 10GHz
Jones Matrix Eigen-Analysis for PMD measurement
Ultra-precise Rubidium frequency standard
Compatible with most third-party tunable lasers

SeBERT-400B is a serial bit error rate (BER) tester for 40 Gb/s serial NRZ signal or 10Gb/s 4 channel parallel NRZ signals. It consists of four 10Gb/s pulse pattern generator (PPG), four 10Gb/s error detectors (ED), a 4-1 multiplexer (MUX), a 1-4 demultiplexer(DEMUX), a frequency synthesizer and a frequency multiplier/divider circuit block.
The 10Gb/s PPGs generate pseudo-random bit sequence signal (PRBS) with pattern length of 27-1, 223-1, 231-1. 40 Gb/s multiplexed output is quasi- PRBS (QPRBS) data.
In addition to the 40 Gb/s serial BER test, 10Gb/s 4 channel parallel bit error rate test is also available. The four 10 Gb/s error detectors(ED) receive the four 10Gb/s data from DUT. These EDs count bit errors within a certain time period simultaneously, and output the number of errors and the error rate value, then these values are displayed on a PC screen via a USB port.
Utilizing the built-in frequency variable synthesizer, SeBERT-400B can be operated at any rate between 39.8 and 44.0 Gb/s.

SeBERT-100 is an integrated Pseudo-random Bit Sequence (PRBS) generator, and Bit Error Detector with internal clock recovery circuit. The SeBERT-100E is an electrical model whilst the SeBERT-100S and SeBERT-100X are models with built-in device module slot for SFP+ and XFP transceivers, respectively.
The PPRBS outputs optical NRZ waveform with bit rate within 9.95~11.32 Gbps, with settable data pattern of 27-1, 223-1, 231-1 and a fixed 64-bit user-defined pattern. The instrument is controlled by external computer via a USB port, with full software support, drivers and programming guide for automation.
