In optical measurement technology, different measurement devices are used to test optical fibers. In addition to analyzers and power measurement devices, optical sources that can be readout with the help of monitors are also used.
Optical light sources for the installation and maintenance of fiber optic single-mode and multi-mode networks.
Inexpensive and comprehensive laser and LED emitter models required for the installation, maintenance, and testing of optical fiber networks.
Sources for single-mode fibers and multi-mode fibers, as well as those with up to four wavelengths for applications in FTTx networks and the LAN environment, are available.
ALS LED sources are used particularly in the aerospace industry.
The sources introduced here are designed for single-mode fibers. With wavelengths of 1310 nm and 1550 nm, the common telecommunications wavelengths are covered.
SmartPocketTM OLS-35 laser sources are inexpensive and compact. They can be battery operated or used with a micro-USB port power supply. Calibration is only necessary every three years. Add this laser source to the SmartPocketTM Optical Test Kit.
The OLS2 laser source emits laser light in a continuous wave (cw) or modulated with a test tone (1 kHz or 2 kHz). It is operated using the WaveID method. In this method, the light is coded to allow the receiver to recognize the transmitted wavelength. This leads to a reduction in the testing times. In addition, it is not necessary to set the correct wavelength on the receiver.
The OLS1 LED sources emit at 850 nm and 1300 nm. These units can be used for both 50 µm and 62.5 µm fibers. They can be battery operated or are available with a power supply unit on an optional basis.
OLS-34: For LAN/WAN Access and Enterprise MM Networks
SmartPocketTM OLS-34 multi-mode LED sources can be used in 50/125 µm MM fibers. The central wavelengths include 850 nm and 1300 nm. They can be used with all standard connector types.
Three Wavelengths – The OLS7 Series
The OLS7 series includes laser sources with three wavelengths that are used in the measurement of the insertion loss of single-mode fibers in combination with optical power meters. They are used in the testing of FTTx networks.
The stabilized laser source facilitates reliable test results that meet the current TIA/EIA and ISO requirements. The following types are available:
SmartClassTM OLS-55 and OLS-56
Optical laser sources are emitters with up to 4 wavelengths. Developed for applications from PON to gigabit Ethernet, these level transmitters are used in the installation, testing, and maintenance of single-mode and multi-mode networks. These laser sources feature an adjustable output level, an excellent power supply management system, and a USB port for remote control. The quick start feature without any warm-up time and the illuminated graphic display allow this device to be used anytime. The large storage capacity of the SmartClassTM laser sources is enough for up to 1000 test results with an automatic date and time stamp.
This single measurement instrument combines four wavelengths for the measurement of MM fibers and SM fibers. The SmartPocketTM OLS-36 laser source is equipped with the following wavelengths: 850 nm, 1300 nm, 1310 nm, and 1550 nm.
OLS4 Quad Output with Wave ID
The output ports of the combined LED/laser source are as follows:
The following output options are available for selection: cw, WaveID, or dual wavelength WaveID. WaveID yields shorter testing times: Each wavelength is coded with a unique WaveID code. Together with the corresponding power meter, two wavelengths can be transmitted and received simultaneously per test. This increases efficiency and saves time.
Both 850 nm and 1300 nm ALS LED sources are used in the measurement of multimode fibers; they guarantee stable 85%/85% coupling conditions. This device is designed for 62.5/125 µm and 50/125 µm fibers.
This compact source is operated via Li ion batteries, which last 48 hours.
