VOA Module with Tap Monitor in
SFP Form Factor
VOAM Series
Product Description
Oplink’s Variable Optical Attenuator Module (VOAM) integrates a single chan-
nel VOA and tap monitor into MSA compliant compact SFP form factor and
provides I2C communication interface for easy system integration. Key features
include compact size, high levels of functional integration and simple network
application. The SFP VOAM is designed for key network optical power man-
agement.
Oplink can provide customized designs to meet specialized feature applica-
tions. Also, Oplink offers modular assemblies that integrate other components
to form a full function module or subsystem.
