Spectronix unveils wavelength tunable 10G bit error rate testers
Spectronix Inc. says it has added the Eye-BERT 10G and the Eye-BERT Micro 10G 10-Gbit bit error rate testers (BERTs) to its Eye-BERT product line. The two new BERT fiber-optic test and measurement systems are designed to combine low-cost and high performance via features not found in other test equipment.The units are engineered to be simple to use and versatile, thanks to the use of standard XFP transceiver modules. The modules enable users to customize the interface for the fiber types and wavelengths of concern.The Eye-BERT Micro 10G, as its name implies, is a small unit with an externally pluggable XFP transceiver and USB interface. The Eye-BERT 10G has front panel controls and an internal transceiver. Both units support full C-Band wavelength tuning.The two BERTs operate between 9.9 and 11.4 Gbps with user-selectable test patterns. The units can generate nonstandard bit rates that the user can program in 10-Hz steps. Users also can employ custom programmable 64-bit patterns including unbalanced signals that can be valuable for CDR margin testing. The Windows user interface and custom bit rate and pattern generator features combine to form an optical signal generator able to produce modulated optical signals between 155 MHz and 5.7 GHz.Another feature of the Eye-BERT Micro 10G that network installers may find useful is its ability to decode and automatically test XFP transceivers. XFP identification and testing is accomplished without having to look up the transceiver specifications, Spectronix says. Inserting an XFP with a loopback cable and initiating the Test XFP function will cause the Eye-BERT Micro 10G to read the transceiver registers and automatically test the device performance against the specifications read. The system will generate a test report within 20 seconds that includes part number, serial number, date code, operational specifications, diagnostics, functional test results, BERT results, and overall pass/fail results, Spectronix says.The Eye-BERT 10G is offered in a stand alone bench top package with full front panel controls as well as USB interface. Standard configurations include 850 nm, 1310 nm, 1550 nm, and C-Band Tunable; other options including DWDM outputs are also available. The Eye-BERT Micro 10G measures 3.5x2.5x1.2 inches and comes with optional flange mounts.Both units come with a power supply, USB driver, and Windows software application; the communication protocol is designed to makes user application development and integration into automated test equipment straightforward. Target applications include use in the lab, by network installation professionals, and for integration into larger systems or ATE to provide dedicated link verification.
General Photonics offers TCA-1000 SmartLight Tunable ASE Source for 40G signal emulation
General Photonics has announced general availability for its TCA-1000 SmartLight tunable amplified spontaneous emission (ASE) source with 50-GHz channel spacing on the ITU grid. The fully polarized light source features a FWHM bandwidth of 0.3 nm. The TCA-1000 SmartLight is designed to emulate a 40-Gbps signal for polarization mode dispersion (PMD) effect tests, in-service link PMD measurement, PMD compensator evaluation, WDM channel testing, 40G system testing, and 40G optical component testing.The TCA-1000 features a built-in polarization rotator allowing its use in conjunction with General Photonics’ PMDPro PMD-1000 polarization optimized PMD source to monitor or measure the PMD of an in-service WDM channel. It can also be used to evaluate the performance of PMD compensators with DOP feedback. Other applications include measuring spectrum-averaged values of parameters such as the insertion loss (IL), polarization dependent loss (PDL), and return loss (RL) of a fiber component on a 40-Gbps signal for each WDM channel. The TCA-1000's polarization rotator rotates the output polarization by 45 degrees with a speed of 0.2 ms."It's no secret that PMD can have undesirable performance impacts on fiber-optic data transmission links exceeding 10 Gbps," said Steve Yao, president of General Photonics. "One of the major applications of the TCA-1000 is to aid our PMDPro to accurately measure the PMD values of in-service optical light paths with 50-GHz spacing. Measurement on in-service links delivers advanced performance insight into service provider networks."The TCA-1000 operates in the C-Band. The wavelength channel can be tuned either via the front panel keypad or via the communication ports on the rear panel. Tuning speed is less than 10 s, the company asserts. Standard communication interfaces include RS-232, USB, Ethernet, and GPIB. Maximum power output is 16 dBm and the power attenuation range is 20 dB. The output power level can be controlled via an internal VOA. Short-term power stability is 0.004 dB over 1 minute and long term power stability is 0.05 dB for more than 8 hours.
Data-Tester offers ProtocolBox for 10G BER, PRBS, and SONET/SDH testing
Emerging Montreal-based test equipment company Data-Tester has launched its first product, the ProtocolBox. The transparency testing instrument is a low-cost, compact unit aimed at small and medium-sized companies that require transport testing for R&D, verification, and subcontract purposes.The ProtocolBox is engineered to provide flexible transport testing, including BER, PRBS, and SONET/SDH, OTN, and Fibre Channel testing at rates up to 11.3 Gbps. The 5-inch square box includes five optical ports for traffic generation and monitoring, including Web-based browser management.“We started the design process with three goals in mind,” says Jean-Lou Dupont, founder and president of Data-Tester. “Dramatically lower the cost of testing equipment, simplify the operating procedure, and ensure quick and direct purchasing processes. “Our goal is to provide an affordable and user-friendly alternative to expensive, full-featured test equipment,” Dupont continues. “Most users only use a small subset – about 20% of the features for generating and monitoring traffic integrity. The ProtocolBox targets these users.”Data-Tester describes the ProtocolBox as an alternative to such fiber-optic testing instruments as the Agilent/HP OmniBER and Digital Lightwave NIC NXG. The ProtocolBox is scheduled for availability by mid-May, but interested parties may be able to secure a pre-release by contacting Data-Tester directly.Data-Tester plans to unveil additional products toward the end of the year.
