Model 755MM-M Optical Transmitter
1550 nm, 10 km, High SBS Suppression
Ortel’s Model 755MM-M is a recently developed 1550 nm transmitter
suitable for link lengths of up to 10Km. The 75Ω
RF video input
supports frequencies up to 870 MHz. A 50Ω RF input supports
frequencies up to 2200 MHz for FTTP, L-Band satellite, and wireless
applications.
Also integrated into the RF/Optical design are Ortel’s low chirp control
and noise suppression circuitry. Integrated within the design is Ortel’s
patented pre distortion technology to provide outstanding performance
with any of Ortel’s wide range of cooled broadband lasers. These
modules have optional dual redundant power supplies and SNMP
capability.
It features Ortel’s proprietary Enhanced Optical Spectrum Reshaping
Technology with extremely high SBS suppression performance, making
it ideal for either FTTP or HFC network applications. The performance
specifications indicated below are subject to change.
