10 Gbits/s Lithium Niobate Electro-Optic Modulator
Data Sheet
May 2001
Optical/Electrical Characteristics (continued)
Electrical Signal Input
Electrical signal input is made through SMA coaxial connectors. The standard device includes an internal termina-
tion network. Care must be taken not to exceed the recommended 8 in./lb. of torque when making connections to
these inputs. High-frequency coaxial cable is recommended.
