Model 755MM-X (3980E) Optical Transmitter
1550 nm, 65 km, Low Distortion
Emcore’s Model 755MM-X is a recently developed 1550 nm transmitter
suitable for link lengths of up to 65 km. The 75Ω RF video input
supports frequencies up to 870 MHz. Also integrated into the RF/Optical
design are Emcore’s low chirp control and noise suppression circuitry.
Integrated within the design is Emcore’s patented pre distortion
technology to provide outstanding performance with any of Emcore’s
wide range of cooled broadband lasers. These modules may be made
available with dual power supply options and SNMP capability.
Applications
ꢀVideo signal distribution to
HFC CATV and FTTP nodes
The 755MM-X adopts the Hybrid Modulation (patent pending) scheme
with superior performance, which is similar to that of External
Modulation and easy tuning which is similar to that of Direct Modulation,
making it ideal for either FTTP or HFC network applications. The
performance specifications indicated below are subject to change.
