Thorlabs' RXM Series of Ultrafast Receivers includes multimode and single mode fiber-coupled photoreceivers with wide wavelength ranges. The core element of each receiver is a fiber-coupled, hermetically sealed microwave detector module. For convenience and simplicity of use, the module is mounted inside a rugged aluminum housing that includes current monitor circuitry and a digital display of the DC photocurrent.
Features:
- Models Cover Wavelengths from 700 nm to 1650 nm
- Internal Multimode or Single Mode Fiber with FC/PC Connector
- Maximum Bandwidth from 10 GHz to 42 GHz
- Integrated Photodiode and Low-Noise Transimpedance Amplifier
Our multimode receivers contain Ø50 µm core OM4 multimode fiber (Thorlabs' GIF50E Graded-Index Multimode Fiber) or Ø62.5 µm core OM1 multimode fiber, while our single mode receivers contain Ø9 µm core SMF-28 single mode fiber. Optical input can be coupled from an FC/PC-terminated fiber via the narrow key FC bulkhead connector. Custom units with FC/APC connectors are also available upon request; please contact
RF signal output(s) are available via female 2.92 mm RF connector(s), except for Item # RXM15EF which provides an inverting RF output through a female SMA connector. The RF output signals can be connected to a measurement instrument using suitable microwave cables or adapters. For differential output devices (25 GHz, 33 GHz, 38 GHz, 40 GHz, and 42 GHz RXM receivers), one input is inverting and the other is non-inverting, and each output is labeled. If only one RF output is being used, the unused port should be capped with a 50 Ω terminator; two are included with each receiver. Both RF ports may also be used simultaneously. Measurements of the DC photocurrent can be viewed using the digital display, and an SMA jack on the input panel provides the analog current monitor output signal.
While each RXM Series model is designed and intended for operation over the specified wavelength range shown by the solid colored regions above, each will respond with reduced performance to optical inputs at shorter wavelengths, as shown by the partially transparent regions.
