The 8935FC is a four-channel optical to
electrical broadcast-quality fiber optic receiver
module with two electrical outputs per
channel. It can accommodate SD/HD-SDI
video 270 Mb/s to 1.5 Gb/s as well as DVB
ASI, unbalanced AES, and Grass Valley audio
TDM interfaces. The optical circuitry is housed
in dedicated strapmount SFP submodule
devices mounted on the module circuit board.
To construct a four-channel solution, select two
of the SFP-DRX-1 SFP dual receiver devices.
The SFP-DRX-1 supports both 1310 nm
wavelengths and CWDM wavelengths (1270
nm to 1610 nm). This replaceable SFP
optical technology allows for easy upgrade,
reconfiguration, and servicing.
Parameters are controllable via our NetConfig
web browser interface for configuration. The
popular NetCentral application provides health
monitoring for modular products as well as
many other Grass Valley products.
