Product description

NGB8527

The New 1550nm  External Modulaion Fiber Optical Transmitter for Radio & Television NetworksFull C-band wavelength tunable (tuning range>35nm)

Guangtai NGB8527 all C band tunable CATV external modulation 1550nm fiber optical transmitter, is an industry-leading and pioneer product. The tunable range of wavelength: 1528.77~1563.86nm, the adjustable wavelength: >35nm. With the traditional ITU standard wavelength ±0.8nm( ±100GHz ) can tunable, is a completely new concept and application ranges.

  Product featuresFull C-Band tunable, tunable range >35nm0.4nm interval, 89 ITU channels, database storageITU cord, Frequency, Wavelength three tunable ways, flexible and convenientFleible tunable speed (<20mS)High wavelength(frequency) lock precision(±0.02nm) and stability (±0.012nm)Excellent side mode suppression, high extinction ratioLow noise, narrow linewidth ( Typ.=0.3MHz )Working frequency bandwidth up to 1050MHzExcellent system CNR,CTB,CSO indexSBS threshold 13 ~ 19dBm continuously adjustable1+1 power backup, support hot plug-ingExcellent cost performance Technical Index
