86109B Module Specifications
86109B module specifications and characteristics apply when a module is installed in the instrument mainframe. The following notes refer to the module specifications listed in this chapter.
All specifications describe warranted performance over the temperature range +10° C to + 40° C (unless otherwise noted). The specifications are applicable after the temperature is stabilized, which occurs after 1 hour of continuous operation and while module calibration is valid. Many performance parameters are enhanced through frequent, simple user calibrations.
Specifications describe warranted performance. Characteristics provide useful, nonwarranted information about the functions and performance of the instrument. Characteristics are printed in green italics.
Factory Calibration Cycle. For optimum performance, the instrument should have a complete verification of specifications once every 12 months.
Nominal Value indicates the expected, but not warranted, value of the parameter.

| 1310 nm | 12 V/W |
| Impulse Risetime (10% to 90% measured from impulse response) | 8.5 ps |
| Impulse Pulsewidth (FWHM measured from impulse response) | 12 ps |
| Measured with optical pulses with 5 ps FWHM, 10 Gb/s repetition rate, and 2 mW peak power. | |
| Impulse Aberrations (characteristic) | < 10% peak-to-peak |
| Polarization Dependent Loss (PDL) | < 0.5 dB |
| RMS Noise | |
| Characteristic | 50 μW (best pulse integrity mode) 20 μW (best noise performance mode) |
| Maximum | 70 μW (best pulse integrity mode) 30 μW (best noise performance mode) |
| Measured with modules set at 1310 nm O/E conversion (responsivity) mode. | |
| Scale Factor | |
| Minimum | 20 μW/division |
| Maximum | 1.0 mW/division |
| CW Accuracy (single marker, referenced to average power monitor) | ±50 μW ±4% of (reading– channel offset) |
| Offset Range (referenced two divisions from screen bottom) | –6 mW to +2 mW |
| Average Power Monitor (specified operating wavelength range) | –23 dBm to +9 dBm (5 μW to 8 mW) |
| Factory Calibrated Accuracy | ±5% ± 100 nW ± connector uncertainty, 20°C to 30°C |
| User Calibrated Accuracy | ±2.5% ± 100 nW ± power meter uncertainty, ± connector uncertainty, <5°C change |
| Maximum Input Power | |
| Maximum Displayed Peak | 8 mW (+9 dBm) |
| Maximum Non-destruct Peak | 50 mW (+17 dBm), or 0.25 pJ per pulse |
| Maximum Non-destruct average | 10 mW (+10 dBm) |
| Maximum non-destruct power is related to the fill factor (duty cycle) of the RZ waveform. The factory specification is defined by using a 20% filled 40 Gb/s pulse train (in other words, 5 ps FWHM and 25 ps period). This concept can also be specified as maximum non-destruct pulse energy. The factory specification is specified with 5 ps FWHM optical pulses and maximum non-destruct power providing that the individual pulse shape is square. | |
| Fiber Input | 9/125 μm |
| Connector for fiber input is user-selectable. | |
| Input Return Loss (HMS-10 connector fully filled fiber) | 30 dB |
