The OptoStar 64657T 1550 nm optical transmitter is an industry-leading, long-life CATV 1550 mn external modulation optical transmitter. This transmitter is installed in a standard 1U high chassis. The 64657T optical transmitter has two optical outputs and can be used for long-distance transmission. The 64657T optical transmitter optimizes the optical module circuit and predistortion circuit, so that it has excellent performance indicators whether in a transmission distance of 65 km or through one or more EDFA relays to transmit more than 100 km. While maintaining excellent CTB and CSO performance, the stimulated Brillouin scattering (SBS) suppression threshold is 16 dBm. The 64657T optical transmitter adopts SBS on-site adjustment technology and electrical dispersion compensation (EDC) technology, so that the transmitter can achieve multiple applications without special customization.
This handbook describes the OptoStar 64657T 1550 nm optical transmitter, its key performance characteristics such as high output power, low distortion, and 16 dBm SBS suppression. It also outlines the available interfaces, including dual‑port optical power output, front‑panel RF connector, LCD display, and SNMP control.
Technical specifications are listed, covering wavelength, laser type, connector type, power consumption, environmental limits, and compliance with international safety and EMC standards. Part numbers and contact information for Cisco are provided for service and support. This manual is written in Chinese.
