PRODUCT INFORMATION
820nm
1A301
High-Performance LED
Datacom
This device is designed for Fibre
Channel 266 Mbps applications and
offers an excellent price/performance
ratio for cost-effective solutions. Its
double-lens optical system results in
optimum coupling of power into the
fiber. And it matches the 1A354 PIN
Photodiode.
