HFBR-4503Z
Best Way to Use POF for 5V TTL Serial:
TX Side (Microcontroller)
--------------------------
MCU TX ──► HFBR-1521 (Transmitter)
GND ─────┬──────────────────────┐
Vcc (5V) ──────────────────────►
RX Side (Receiver)
-------------------
POF Fiber ──► HFBR-2521 (Receiver)
Output ─────► MCU RX

🧩 2. Integrated Fiber Optic Transceivers
These are dedicated fiber optic ICs that handle the light/electrical signal conversion for analog or digital baseband signals — suitable for video.
🔹 Avago HFBR-0500 Series (Now Broadcom)
-
HFBR-1521 – Transmitter
- HFBR-2521 – Receiver
✔ Features:
- Accept analog or digital signals (bandwidth limited to ~50 MHz)
- Compatible with 1 mm Plastic Optical Fiber (POF)
- Accepts TTL or analog-like baseband signals
- Can work with buffered composite/S-video signals
Note: For pure analog video, you’ll need pre-emphasis or buffering before the transmitter to match signal levels.
