APPLICATIONS
Amplified DWDM networks
Bandwidth aggregation
Ring topologies with OADM
Finisar’s Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM
transport with dramatically lower power and cost in a standard pluggable Small Form
Factor Pluggable (SFP) package. The FWDM-1629 is designed expressly for service
providers deploying DWDM networking equipment in metropolitan Ethernet and SAN
networks. The fiber link budget has been enhanced to 30dB with an Avalanche Photo
Diode (APD) receiver.
In addition, digital diagnostic features are implemented as described in Finisar
Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”
