CHP Max5000 1 GHz CWDM Forward Path Transmitter —The CHP Max5000 Advanced 1GHz CWDM Transmitter is ideal for MSOs that need to support growing residential and business services on a fiber-scarce HFC plant. The ITU G.695 standards-based CWDM transmitter is available at a wavelength of 1311±4nm with variable output power levels of 4, 6, 8, 10, or 12dBm and with fixed output levels of 13, 14, and 15dBm. This transmitter is also available at a wavelength of 1291±4nm with a variable output with a maximum power of 8dBm. By deploying 1311nm CWDM transmitters, the adjacent ITU channel at 1291nm can be used in CWDM applications to increase the existing capacity of the HFC networks. CHP Max5000 1GHz CWDM transmitters enable customers to support rapidly growing residential and business services while leveraging existing network infrastructure and provides the capability to multiplex two forward wavelengths on a single fiber. In many cases, multiple return wavelengths can also be carried on the same fiber. CHP Max5000 1GHz CWDM transmitter’s variable optical output power range enables operators to reduce spare inventory up to 60 percent, reduce the need for optical attenuators, and adjusted for unexpected link loss during system implementation. These benefits translate into significant CapEx and OpEx savings, and provide maximum flexibility for deploying advanced interactive services. The 1GHz Transmitter’s dual-input capability provides isolation that is much superior to alternative offerings, enabling simultaneous advanced service deployment of video and telephony. In addition, integral high isolation eliminates having to add external devices to achieve similar performance, thereby lowering CapEx even further and reducing system complexity.
