The ARRIS DT4250 Digital Transceiver is a component of ARRIS’s fifth generation Universal Digital Return Platform. It digitizes either one or two discrete legacy RF return path signals from separate inputs. The module’s optical transmit/receive ports are implemented with plug‐in transceivers for ultimate flexibility and affordability. Conforming to the Small Form Factor Pluggable (SFP) Multisource Agreement, these state‐of‐the‐art transceivers are available in a variety of transmit/receive wavelengths, including dedicated 1310 nm and 1550 nm, CWDM (15 wavelengths), and DWDM (40 wavelengths). There are three data rate options of 2.125, 3.1875, or
4.250 Gbps with their selection being dependent upon bandwidth and transceiver configuration.
The DT4250 can support 5‐45 MHz, 5‐65 MHz, 5‐85 MHz up to 5‐100 MHz return bandwidths, and a simple upgrade enables the operator to convert any module to a higher return bandwidth, driven by their network needs.
