Fiber-optic link connects 10-GHz signals

FIBER-OPTIC technology has improved steadily in recent years to where optic al links are now viable replacements for coaxial lines even at bandwidths a s wide as 10 GHz. The MDD series from MITEQ, Inc. (Hauppauge, NY) is such a family of high-speed, high-bandwidth links, offering a 3-dB bandwidth of 1 to 11 GHz with low noise figure and generous link gain over single-mode fi ber-optic cables. The links feature 50-Ohm input (I) and output (O) interfa ces for ease of connection to RF and microwave systems.
