1550nm Single Output EDFA (LB1550D Series)

Lindsay Broadband LB1550D series of rack mount Erbium Doped Fiber Amplifiers (EDFA) are low noise, high performance Optical Amplifiers with single Optical output powers from 14dBm to 23dBm, in 1dBm steps.

The LB1550D series provide optical isolation on the input and output for stable, low noise operation. Auto output power stability control (APC) and auto temperature control (ATC) are standard features. The LED front panel display is used to provide monitoring and associated alarms for all vital parameters. The LB1550D is equipped with RS-232, RJ45 communication interfaces for system network management. Powering is 110V – 240VAC or 40 – 72VDC. Optional hot-swappable dual switch mode power supplies.
