SFP Optical Plug-in Cartridges

The SFP optical plug-in cartridges are small, hot-pluggable devices used to provide fiber connectivity to the 3Gbps/HD/SD products. By using single-mode fiber instead of coaxial cables, these interfaces can be used over much longer distances without degrading signal quality, very useful when carrying 3 Gbps signals.

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 1 or 2 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 optical plug-in cartridges can be easily added at any moment in the field without any service disruption to existing coaxial services, allowing the building of future-proof infrastructures while minimizing initial roll-out costs.

SFP cartridges can accommodate for 1 or 2 fiber connections on LC/PC optical connectors. Miranda 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.

Note: All receiver channels (R) are wideband (except for WDM receivers), responding to wavelengths ranging from 1260 to 1620 nm, compatible with standard 1310 nm and CWDM wavelengths.
