Catv band dual output modulator

COMMUNICATIONS COMPONENTS
CATV Band Dual Output Modulator
Key Features
• Flat frequency response
• Two optical output ports
• Integrated phase modulator
• High optical damage threshold
Applications
The JDSU community antenna television (CATV) band dual output modulator iswidely accepted for use in externally modulated 1550 nm transmitters. Two optical outputs offer flat frequency response and excellent composite second order distortion (CSO) performance. This product is rated for operation atoptical power levels to 200 mW.
A dedicated production line and strict process control measures ensure minimalvariation in device-to-device characteristics.
Typical Frequency Response, S21
Typical Return Loss Curve, S11

Operating temperature
1. All measurements made at 23°C unless otherwise noted.
2. Insertion loss is measured at the maximum of the modulator’s transfer function and does not include the 3 dB loss incurred when operated at quadrature.
3. The bias point of this device is most stable when operated with applied DC voltage close to 0 V.
4. For an 80 channel NTSC, 3% OMI CATV link, with correctly operating modulator bias control, 0.26° delta phase yields a maximum of 68 dBc CSO on both outputs.
