SFP cartridges can directly slide into any product offering SFP connectivity. Within the Densité family, compatible rear panels use an easily identifiable -F extension at the end of the part number to signify SFP cartridge hosting capability. SFP cartridges offer either one or two fiber connections, available as single Tx or Rx, dual Rx, dual Tx or as a bidirectional Rx/Tx. Efficiency can be increased by transporting two channels on a same fiber using WDM Series SFP cartridges. For more demanding applications, up to 18 channels can be multiplexed onto a single fiber using SFP cartridges from the CWDM family (external CWDM mux/demux required), minimizing transmission costs related to the use of metropolitan dark fiber.
SFP cartridges can accommodate for one or two fiber connections on LC/PC optical connectors. Grass Valley SFP nomenclature indicates the availability of optical terminals and light direction using R and T letters for Receive and Transmit channels respectively. The transmitter SFP models (T) also contain transmission method and wavelength information. S is used for single 1310 nm wavelength, W for WDM wavelengths and C for CWDM wavelengths. A number follows and uniquely identifies the wavelength used by a specific transmitter channel.
Single wavelength (1310 nm) is used to carry one 3Gbps/HD/SD SDI signal per fiber link. Ideal for long-distances/point-to-point signal deliveries of a single SDI signal.
SFP cartridges from the CWDM series generate wavelengths compatible with the use of external CWDM mux/demux that can be used to carry of up to 18 different SDI signals onto a single fiber strand. SFP cartridges from this series are dual channel and generate 2 adjacent CWDM wavelengths. The RR SFP Cartridge used for CWDM applications is the same as the one used in with the Single Wavelength Series since the receivers are wideband.
