Note: Rated Fiber coupled power apply only on the TO-46 package,
for housing options fiber coupled power is typically 10% less
TO-46 Package with Lens
Description
This device is designed for Ethernet 100 Mbps and
Intra-Office Telecom 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.
