The JDS Uniphase HA97E+10KSU1 is a programmable optical attenuator for precise control of optical power across telecommunications and laboratory environments. It delivers attenuation up to 100 dB with 0.01 dB resolution and ±0.03 dB typical accuracy, making it suitable for power meter calibration, BER testing, and EDFA characterization. The unit accepts front-panel keypad control, GPIB, and RS232 commands via SCPI/HP8156A-compatible protocol. SC/APC connectors provide optical interfacing, with optional internal couplers (10/90, 50/50, 2/98, 30/70) and 1:2 switch capability for multi-port applications.
