Model 755MM-S Optical Transmitter
1550 nm, 20 km, High SBS Suppression
Ortel’s Model 755MM-S is a recently developed 1550 nm transmitter
suitable for link lengths of up to 20Km. The 75Ω RF video input
supports frequencies up to 870 MHz. 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 dual redundant power
supplies with SNMP capability.
