Description
Single mode FBT Coupler offer very low insertion loss, low polarization dependence and excellent environmental stability. The output can be 1×2, 1×3, 1×4, 1×8, 1×12, 1×16 ,1×32, 1×64 split ratio, but the mostly used are 1×2 and 1×3, due to the more outputs, the welding cost is higher than PLC splitter, so PLC splitter will be used more. The output can be 900um, 2.0mm, 3.0mm loose tube, single mode or multimode fiber are available with very tight uniformity in a wide wavelength range 850nm, 1310nm, 1490nm, 1550nm windows.

Features
- Three types of precision instrument testing: bare fiber testing, air tube testing, assembly testing, telecom level standard, stable and user-friendly.
- Multi process testing: Spectral ratio testing, end face testing, and attenuation testing must all meet the standards before packaging and shipping.
- Full light year structure, good environmental stability, loss insensitive to transmission wavelength, can meet the transmission needs of different wavelengths.
- A-grade plug-in, stable optical signal transmission, high back box reflection, low attenuation, good interchangeability, and even light splitting.
- New ABS plastic synthetic resin shell with impact resistance, heat resistance, and low temperature resistance.
