1 MBd Link
(High Performance HFBR-15X2/25X2, Standard HFBR-15X4/25X4)
System Performance Under recommended operating conditions unless otherwise specified.
Notes:
1. For I
2. The propagation delay for one meter of cable is typically 5 ns.
3. Estimated typical link life expectancy at 40 C exceeds 10 years at 60 mA.
4. Pulsed LED operation at I
