0˚C to +70˚C unless otherwise noted.
Notes:
11. Output power with 200 m hard clad silica optical fiber assumes a typical –10.5 dB difference compared to 1 mm plastic optical fiber.
10. Pins 1 and 4 are for mounting and retaining purposes, but are electrically connected; pins 5 and 6 are electrically isolated. It is recommended that
1. Typical data at 25˚C.
2. Optical power measured at the end of 0.5 meters of 1 mm diameter plastic optical fiber with a large area detector.
3. Minimum and maximum values for P
4. Thermal resistance is measured with the transmitter coupled to a connector assembly and fiber, and mounted on a printed circuit board.
5. To further reduce the thermal resistance, the cathode trace should be made as large as is consistent with good RF circuit design.
6. For I
7. 1.6 mm below seating plane.
8. Minimum peak output power at 25˚C is –5.3 dBm (POF) and –16.0 dBm (HCS
9. Optical power measured at the end of 1 meter of 1 mm diameter plastic or 200 m hard clad silica optical fiber with a large area detector.
