SFW-BS Band splitter

SFW-BS Band splitter

The compact SFW-BS band splitter series is designed to be used for FTTH projects in passive optical network (PON) infrastructures. The SFW-BS shall be used for combining and splitting of wide wavelength range:
Type SFW-BS-31-49/55 combines a data signal wide wavelength bandwidth 1270 - 1537.5 nm  with wavelength range 1542.5 – 1620 nm of analog or digital CATV signal.
Type SFW-BS-31-55/62 is used for separating 1625 nm from the rest of whole signal band, usually for measuring purposes. 
Various types of pigtails and connector terminations are available to meet your requirements.
