HFBR-0508 Datasheet, PDF (3/8 Pages) AVAGO TECHNOLOGIES LIMITED – 10 Megabaud Versatile Link Fiber Optic Transmitter and Receiver for 1 mm POF and 200 μm HCS®

HFBR-1528 Transmitter
The HFBR-1528 transmitter incorporates a 650 nm LED in
a light gray, nonconductive plastic housing. The high light
output power enables the use of both plastic optical fiber
(POF) and Hard Clad Silica (HCS) fiber. This transmitter can
be operated up to 10 MBd using a simple driver circuit. The
HFBR-1528 is com­pat­ible with all Versatile Link connectors.

Notes:
1. Typical data are at 25°C.
2. Optical power measured at the end of 0.5 meters of 1 mm diameter plastic or 200 µm diameter hard clad silica 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. Typical value measured from junction to PC board solder joint for horizontal mount package, HFBR-1528.
5. Pins 5 and 8 are for mounting and retaining purposes, but are electrically connected; pins 3 and 4 are electrically isolated. It is recommended
that pins 3, 4, 5 and 8 all be connected to ground to reduce coupling of electrical noise.
6. Refer to the “Plastic Optical Fiber and HCS Fiber Cable and Connectors for Versatile Link”Technical Data Sheet for cable connector options for 1
mm plastic and 200 µm HCS optical fiber.
