Analog Devices Inc.
Analog Devices Clock synchronizers are designed for wired networking applications, providing the clock redundancy functionality needed to maximize system uptime. Our technology supports clock synchronization with common standards, including 1 pulse per second (PPS) output signal from a GPS receiver. GPS signals are broadly available and utilize an extremely stable atomic clock as its time base, but they are often noisy. Systems rely on the IEEE1588 timing protocol to establish synchronous communications across the wired network, including synchronous Ethernet and synchronous digital hierarchy (SDH) to optical transport network (OTN) mapping/demapping. The IEEE1588 protocol has emerged as the preferred method for Clock synchronizing systems throughout both computer networks and local area networks (LAN).

NFO series -
Radiantech, Inc.
The NFO OTDR unit injects the laser pulse into the fiber under test and picks up scattered and reflected optical signals by an avalanche photodiode (APD). The unit accepts remote commands from Internet to control all related timing and data acquisition processes. Maximal three wavelengths are available at the NFO with options on 1310, 1490, 1550, and 1625 nm. NFO also has options on dynamic ranges so users can select the most cost effective units for their demands. Radiantech provides an easy use API (Application Program Interface) for NFO so users can design and build their own AP for NFO. Standard NFO API package is for Windows XP or higher. Please contact Radiantech’s sales person to inquire API for another OS.

Edmund Optics Inc.
These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.

mks Ophir
Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω
