PRODUCT INFORMATION
820nm
1A388
High-Performance LED
Datacom, Intra-Office Telecom
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. And
it matches the 1A354 PIN
Photodiode.

PRODUCT INFORMATION
SMA-2A
Package
Emitter or Detector in SMA Package
Mitel emitters and detectors can be
provided in this low-profile SMA
package. The device is electrically
isolated from the SMA receptacle to
facilitate electrical connection. And
optimum fiber-coupled power or
responsivity is ensured by active
alignment against the fiber.
