Frequently Asked Questions
Q: What split ratios are available?
A: 1x2, 2x2, 1x4, 1x5 and 1x8 configurations are available in bare fiber, steel tube or ABS box packages.
Q: What operating wavelengths are supported?
A: Standard operating wavelengths include 1310nm, 1490nm, 1550nm and dual-window 1310/1550nm versions.
Q: What is the typical excess loss?
A: Typical excess loss is 0.4dB or less with excellent uniformity, making FBT couplers a cost-effective solution for PON and CATV distribution.
Q: Can samples be provided for testing?
A: Yes, samples are available. Please contact our sales team with the model, ratio and connector requirements.
