Transmission bandwidth(-30dBm): ~0.28nm, Reflection bandwidth(-22.5dB): about 0.7nm, so we believe they are 50GHz FBG. (temperature=25 C).With individual test data, transmission and reflection spectrum, as shown as the photos (photos are only samples, wavelength is different if P/N is different). Please check available wavelength, qty, and price at the description bottom below.
