E-Band Bismuth-doped Fiber Amplifier

Amonics’ E-Band Bismuth-doped fiber amplifier (BDFA) uses bismuth-doped fiber as the gain medium. The BDFA features high small signal gain and low noise figure. The silica-based Bismuth-doped fiber offers the similar fundamental advantages as erbium-doped fiber used for amplification in the C and L bands. The E-band BDFA are available to fulfill the increasing bandwidth demands.

The turnkey microprocessor-controlled BDFAs provide illustrative alarms and status indicators. An integrated RS232 computer interface enables easy control, diagnostic functions and data acquisition. The BDFAs are available in both benchtop and rackmount casings.
