Notes:

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.

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.

7. 1.6 mm below seating plane.

9. Optical power measured at the end of 1 meter of 1 mm diameter plastic or 200

µm hard clad silica optical fiber with a large area detector.

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 pins 1, 4, 5, and 6 all be connected to ground to reduce coupling of electrical noise.

11. Output power with 200

µm hard clad silica optical fiber assumes a typical –10.5 dB difference compared to 1 mm plastic optical fiber.
