86111A Module Specifications
86111A 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.
| Item | Description |
|---|---|
| Each channel of a dual optical module meets the published specifications. There is no specification of relative performance between the two channels. However, characteristics of individual channels may vary. | |
| Optical Channel Unfiltered Bandwidth | 2.85 GHz, high sensitivity (3 GHz typical) |
| Wavelength Range | 750 to 860 nm |
| Calibrated Wavelengths | 850 nm |
| Filter/Data Rates (Mb/s) | |
| 86111A-201 | OC-3/STM-1 (155) OC-12/STM-4 (622) |
| 86111A-202 | Fibre Channel (1063) Gigabit Ethernet(1250) |
| Optical channel specifications are warranted for muti-mode inputs only. | |
| Sensitivity (Characteristic - smallest average power for mask test) | –17dBm |
| Transition Time (10%to 90% calculated from TR = 0.48/BW optical) | 160 ps |
| RMS Noise | |
| Characteristic | 1.5 μW |
| Maximum | 2.5 μW |
| Scale Factor | |
| Minimum | 5 μW/division |
| Maximum | 100 μW/division |
| CW Accuracy (single marker, referenced to average power monitor) | ±6 μW ±0.4% of full scale ±3% of (reading – channel offset) |
| Offset Range (referenced two divisions from screen bottom) | +0.2 mW to -0.6 mW, |
| Average Power Monitor, Specified Operating Range | –30 dBm to –2.2 dBm |
| Factory Calibrated Accuracy | ±5% ± 100 nW ± connector uncertainty, 20°C to 30°C |
| User Calibrated Accuracy | ±2% ± 100 nW ± power meter uncertainty, < 5°C change |
| Maximum Input Power | |
| Maximum Non-destruct Average | 0.4 mW (–4 dBm) |
| Maximum Non-destruct Peak | 10 mW |
| To guarantee that waveforms with large overshoot do not saturate the channel, average power should be kept below –10 dBm. | |
| Fiber Input | 62.5/125 μm |
| Connector for fiber input is user-selectable. | |
| Input Return Loss (HMS-10 connector fully filled fiber) | 20 dB |
