Notes:
1. 2.0 mm from where leads enter case.
2. Typical data at T = +25° C.
A
3. Thermal resistance is measured with the transmitter coupled to a connector assembly and fiber, and mounted on a printed circuit board.
4. Pins 2, 6, and 7 are welded to the cathode header connection to minimize the thermal resistance from junction to ambient. To further reduce the
thermal resistance, the cathode trace should be made as large as is consistent with good RF circuit design.
5.
P is measured with a large area detector at the end of 0.5 metre of plastic optical fiber with 1 mm diameter and numerical aperture of 0.5.
T
6. When changing W to dBm, the optical power is referenced to 1 mW (1000 W). Optical Power P(dBm) = 10 log [P (W)/1000 W].
7. Measured at the end of 1mm plastic fiber optic cable with a large area detector.
8. 8 mA load (5 x 1.6 mA), R = 560 .
L
9. Propagation delay through the system is the result of several sequentially occurring phenomena. Consequently it is a combination of data-rate-
limiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in terms of time differentials
between delays imposed on falling and rising edges. As the cable length is increased, the propagation delays increase. Data-rate, as limited by
pulse width distortion, is not affected by increasing cable length if the optical power level at the receiver is maintained.
10. Pulse width distortion is the difference between the delay of the rising and falling edges.
11. Both HFBR-1602Z and HFBR-1604Z meet the SERCOS "low attenuation" specifications when operated at 35 mA; only HFBR-1604Z meets the
SERCOS "high attenuation" limits when operated at 60 mA.
