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.
3. Minimum and maximum values for P
T
over temperature are based on a fixed drive current. The recommended drive circuit has temperature
compensation which reduces the variation in P
T
over temperature, refer to Figures 4 and 6.
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
F,PK
> 60 mA, the duty factor must maintain I
F,AVG
≤ 60 mA and pulse width ≤ 1 µs.
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
®
) for 1505C series only.
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.

HFBR-25x5A/B Receivers
The HFBR-25x5A/B receiver
consists of a silicon PIN
photodiode and digitizing IC to
produce a logic compatible
output. The IC includes a unique
circuit to correct the pulse width
distortion of the first bit after a
long idle period. This enables
operation from DC to 10 MBd
with low PWD for arbitrary data
patterns. The receiver output is a
“push–pull” stage compatible with
TTL and CMOS logic. The receiver
housing is a dark grey, conductive
plastic. The HFBR-2505A is
compatible with SMA connectors,
while the HFBR-2515B mates with
ST
®
connectors.
