LTS1500 光损耗测试仪光纤通讯 Loss Test Set-LTSThe FTE-4000 TTI Hand Held Variable Optical Attenuator is available in two models, with 40 dB attenuation level or 80 dB attenuation level to meet single mode testing requirements. Like the rest of the FTE line, the VOA has an onboard help feature. The FTE-4000 has a built in output power monitor to assist in setting the appropriate attenuation levels and a sweep mode which can scan the attenuation across desired levels. It is rugged with a splash proof housing with a highly protective boot. The FTE-4000 can assist in the testing of system budget compliance, balancing transmitter power and adjusting receiver attenuation settings.Features? Integrated Power Meter? Up to 80 dB Attenuation?

FTE5000 损耗测试仪 带ORL和视频探头The FTE-5000 combines four functions for testing optical networks together in one unit. It brings together a -55dB ORL meter, power meter, laser source and video scope capability with IEC61300-3-35 method “B” Pass/Fail End face Grading Map (probe sold separately). The FTE-5000 is a full featured ORL Loss Test Set. It has 4” super bright color touch screen display with large easy to read characters. It performs optical return loss measurements to -55db at up to three wavelengths and is an automated loss test set with dual or triple wave Light sources. The power meter uses an InGaAs detector which is calibrated at 850,1300, 1310, 1490, 1550 and 1625nm, with a dynamic range of -77dBm. These units are available in single, dual, triple or quad wavelength configurations and displays measurements up to three wavelengths at one time. In the Autotest mode, the master unit changes wavelengths at a fixed rate and informs the slave unit of the wavelength currently being measured. Use this method to test up to three wavelengths at a time and store the loss measurements for each of the lasers fired during the test. Up to 5000 tests may be stored and recalled via the unit’s USB port. Use TTI’s CertSoft PC application software for downloading stored data and organizing the information or use the Android Bluetooth virtual instrument application for remote operation. The information from OTDR, LTS, ORL and video scope may be combined to offer a comprehensive report for all of your network testing needs. The FTE-5000 also includes a video scope (probe sold separately). Use the video scope to ensure the integrity and cleanliness of the connectors being tested. Use the modulation feature to perform fiber identification function. The power meter will identify modulated signals at 270, 1000 and 2000 Hz produced a modulate light source.
