1550 nm Single Output EDFA (LB5155D Series)

Lindsay’s LB5155D series of rack mount Erbium Doped Fiber Amplifiers (EDFA) are low noise, high performance optical amplifiers with single optical output powers from 14 dBm to 24 dBm, in 1 dBm steps.

The LB5155D EDFAs 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 LB5155D EDFAs are equipped with RS-232, RJ45 communication interfaces for system network management. Powering is 110-240 VAC or 40–72 VDC. Optional hot-swappable dual switch mode power supplies are available.
