PRODUCT INFORMATION
860nm ^1A194
Datacom, General Purpose
High-Performance LED
This device is designed for Ethernet
and general applications and offers
an excellent price/performance ratio
for cost-effective solutions. Its dou-
ble-lens optical system results in
optimum coupling of power into the
fiber.
