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.

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.

The new Yokogawa AQ6373 is an optical spectrum analyser designed to carry out measurements over the wavelength range from 350 to 1200 nm, including the visible light spectrum from 380 to 780 nm.

In addition to its world-class optical performance in areas such as resolution, accuracy, sensitivity, measurement speed and dynamic range, the AQ6373 features a colour analysis function which makes it ideally suited to measurements on LEDs and laser light sources.

Key performance parameters include a wavelength accuracy of ±0.05 nm, a wavelength resolution down to 0.01 nm, and a sensitivity of -80 dBm, switchable to a choice of high dynamic-range modes.

High-speed measurements result from a standard sweep time down to one second (0.5 sec in automatic mode), while the free-space optical input makes the instrument applicable to use with single-mode, multimode, and large-diameter-core fibres. A built-in light source is also provided to aid optical alignment.

The AQ6373 offers excellent functionality and operability, with ease of operation and data handling. The large (10.4-inch) bright display features an intuitive graphical user interface, and operation can be controlled via USB mouse and keyboard as well as panel keys.

 

The Yokogawa AQ2210 Series is a new version of the company’s multi-application test system: a modular system designed to offer a wide range of measurements on optical devices and optical transmission systems.

The new product is a successor to Yokogawa’s established AQ2200 system, and is 100% backwards compatible with the earlier product. New features in the AQ2210 Series include enhancements to remote-control capabilities, multi-user functionality, macro programming, and remote viewer software.

The AQ2210 Series offers a choice of 3-slot (AQ2211) or 9-slot (AQ2212) mainframes, each of which can be used with any of the existing AQ2200 Series modules and remote commands. Each mainframe incorporates a bright display with an added ‘print screen’ key, USB, GP-IB and Ethernet interfaces, and an additional front-panel USB storage interface. Modules can be ‘hot-swapped’, with the mainframe automatically recognising installed or removed modules.

Quick response under remote control results from fast command processing and fast data and command transfer via a high-speed LAN (which is 100BASE-TX compatible). This capability is particularly effective when repeating a process that a module does not take a long time to complete, such as the continual switching of optical paths or the reading of optical powers.

The new system features faster attenuation setting speed (by up to a factor of 1.7 times). This is particularly important in improving the throughput of optical transceiver testing, where frequent changes of attenuation settings can occur during a measurement.
