Description
The SG4000 scalable optical node offers a wide variety of analog return path transmitter Distributed Feedback (DFBT) technologies to meet the increasing demand for higher modulation and bonded DOCSIS® environments. SG4-DFBT 1 mW and SG4‐DFBT3 2 mW transmitters are 1310 nm, isolated, un‐cooled, Distributed Feedback (DFB) lasers. SG4‐DFBT3-CWDM 2 mW transmitters are available in eight Coarse Wave Division Multiplexed (CWDM) wavelengths. CWDM transmitters offer improved link performance and allow multiple wavelengths to be combined on a single fiber utilizing ruggedized optical passives. SG4-ITU-CH transmitters feature cooled, 8 mWlasers based on the International Telecommunications Union (ITU) wavelength grid for maximum link budgets and wavelength aggregation.
