XLA-100 Series overview

The XLA-100 Series lightwave component analyzer characterizes the high-speed devices of an optical transmission link: modulators, lasers, PIN/APD photodetectors and fiber filters. One instrument measures their bandwidth, amplitude-frequency response, phase-frequency response and group delay, for R&D and production-line testing.

Four models, from the XLA-100-26G5 to the XLA-100-67G, cover a modulation frequency range of 10 MHz to 26.5 GHz up to 67 GHz by model. A one-click broadband sweep returns the full response, and the frequency interval and IF bandwidth are adjustable for each measurement. Besides the internal 1310 nm and 1550 nm sources, an external optical source can be connected for CWDM and DWDM component testing.

The XLA-100 connects the device under test through its optical and RF paths, so electrical, electro-optical, opto-electrical and optical-optical measurements run from the same setup. Each measurement starts with electrical calibration and optical-path parameter calibration, and probe error from chip test fixtures can be removed with de-embedding data.

XLA-100 Series capabilities and applications

The XLA-100 Series switches between its measurement modes from one integrated interface, which covers S-parameter, impedance and time-domain measurements of common devices.

For photodetectors, the XLA-100 runs frequency response tests with rapid 3 dB bandwidth analysis. Phase-frequency response measurement gives the phase and group delay of the optoelectronic device.

The optical toolbox includes a large dynamic range optical power meter that monitors the input optical power in real time. Through the advanced settings, the light-emitting module can be set to CW output. In CW mode the polarization-maintaining laser source output has an extinction ratio greater than 20 dB and supplies an M-Z type modulator.

XLA-100 Series frequently asked questions

What modulation frequency range does each XLA-100 model cover?

The XLA-100 Series modulation frequency range by model is 10 MHz to 26.5 GHz for the XLA-100-26G5, 10 MHz to 43.5 GHz for the XLA-100-43G5, 10 MHz to 50 GHz for the XLA-100-50G and 10 MHz to 67 GHz for the XLA-100-67G. Frequency accuracy is ±1 × 10⁻⁷ and frequency resolution is 1 Hz on all four models.

Which optical wavelengths can the XLA-100 lightwave component analyzer test at?

The XLA-100 internal sources give a working wavelength of 1310 ± 20 nm and 1550 ± 20 nm. Testing is not limited to those two bands, because external optical sources from 1260 nm to 1630 nm can be connected. This covers the core components of CWDM and DWDM systems.

Are the XLA-100 safe optical input limits the same as its measurement range?

No. On the XLA-100, optical input 1 measures average optical power from -35 dBm to +5 dBm and has a +7 dBm maximum safe average input power. Optical input 2 measures -25 dBm to +15 dBm and has a +17 dBm maximum safe average input power. Measurement accuracy is ±0.5 dB on both inputs.

How accurate are XLA-100 group delay and phase measurements?

XLA-100 group delay measurement accuracy is ±13 ps for the XLA-100-26G5, ±18 ps for the XLA-100-43G5 and XLA-100-50G, and ±31 ps for the XLA-100-67G. Phase measurement accuracy is ±3.5° for the XLA-100-26G5, ±4.2° for the XLA-100-43G5 and XLA-100-50G, and ±6.0° for the XLA-100-67G.

Can the XLA-100 measure balanced photodetectors and differential devices?

Yes. The XLA-100 Series can be configured for single-ended to single-ended or single-ended to balanced measurements of optical transmitting and receiving devices. In the balanced configuration it measures differential gain and common-mode rejection, which suits multi-port parameter measurement in high-speed optical fiber communication.

Which XLA-100 Series specifications vary by model or configuration?

On the XLA-100 Series, modulation frequency range (10 MHz to 26.5 GHz; 10 MHz to 43.5 GHz; 10 MHz to 50 GHz; 10 MHz to 67 GHz) varies by model.
