86116A Module Specifications
Instrument:
None
Availability:
Obsolete
86116A 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.

| Best Pulse Fidelity Mode - (characteristic) | 53 GHz |
| Best Sensitivity Mode - (characteristic) | ~50 GHz |
| Default Optical Channel Setting | 50 GHz (Best Sensitivity Mode) |
| Calculated from optical impulse pulse width measurements on an optical impulse: BW = 0.48/FWHM. | |
| Impulse Rise Time (characteristic, 10% to 90% measured from impulse response) | 7.4 ps |
| Impulse Pulse Width (characteristic, FWHM measured from impulse response for Best Pulse Fidelity Mode) | 9.0 ps |
| Measured with optical impulse with a pulse of 700 fs FWHM, 5 MHz repetition rate, and 10 mW peak power. | |
| System jitter less than 800 fs RMS. | |
| Impulse Distortion (characteristic) | < 15% |
| Impulse distortion (%) = [(distortion peak-to-peak)/impulse height] x 100%. | |
| RZ Pattern Dependency: One Level Distortion (characteristic) | < 15% |
| Pattern Dependency: One Level Distortion (%) = [One Level variation/Max One Level] x 100%; measured with 40 Gb/s RZ pattern (32 consecutive bits of RZ "1's") with 6 ps FWHM input pulses resulting in a fill factor of 24%. | |
| RZ Pattern Dependency: Zero Level Distortion (characteristic) | < 20% |
| Pattern Dependency: Zero Level Distortion (%) = [Zero Level variation/Max One Level] x 100%; measured with 40 Gb/s RZ pattern (16 bits "Zero" followed by 16 bits "One") with 6 ps FWHM pulses resulting in a fill factor of 24%. | |
| Average Input Power for Linear Operation using 40 Gb/s RZ Signals (characteristic) | < 4 mW |
| Tested with 40 Gb/s RZ signals with pulses of 6 ps (FWHM). | |
| Polarization Dependent Loss (PDL) (characteristic) | < 0.5 dB |
| RMS Noise | |
| Characteristic | 160 μW (best pulse fidelity mode: 53 GHz setting )
60 μW (best sensitivity mode: ~50 GHz setting) |
| Maximum | 260 μW (best pulse fidelity mode: 53 GHz setting) 90 μW (best sensitivity mode: ~50 GHz setting) |
| Measured one standard deviation from mean, with modules set at 1310 nm O/E conversion (responsivity) mode. | |
| Scale Factor (full height is eight divisions) | |
| Minimum | 200 μW/division |
| Maximum | 2.5 mW/division |

| CW Optical Power Offset (referenced two divisions from screen bottom) | –15 mW to +5 mW |
| Average Optical Power Monitor (1000 – 1600 nm) | –23 dBm to +9 dBm (5 μW to 8 mW) |
| Average Optical Power Factory Calibrated Accuracy | ±5% ± 100 nW ± connector uncertainty, 20°C to 30°C |
| Conditions: CW optical power only (no modulation). | |
| Average Optical Power User Calibrated Accuracy | ±2.5% ± 100 nW ± power meter uncertainty, ± connector uncertainty, < 5°C change |
| Conditions: CW optical power only (no modulation). | |
| Maximum Input Average Optical Power | |
| Maximum Displayed Peak | 20 mW (+13 dBm) |
| Maximum Linear Peak - (characteristic) | 30 mW (+14.8 dBm), or 0.15 pJ per pulse, whichever is less |
| Maximum Non-destruct Peak - (characteristic) | 50 mW (+17 dBm), or 0.25 pJ per pulse, whichever is less |
| Maximum Non-destruct average - (characteristic) | 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 |
| Proper connector care is required to maintain this specification. | |
