Fused couplers are used to split optical signals between two (or more) fibers or to combine optical signals from two (or more) fibers into one fiber. They are constructed by fusing and tapering the fibers together. This method creates a simple, rugged, compact method of splitting or combining optical signals. Typical excess losses are as low as 0.2 dB, while split ratio tolerances range from ±5% to ±0.5% at design wavelengths depending upon the splitting ratio. These devices are bidirectional and offer low backreflection and insertion losses

Power and Wavelength Testing
Test the signal delivering strength and wavelength, to ensure the signal decoding capacity of the receiver, and the wavelength remains consistent from the transmitter to the receiver.
Traffic Testing
Test the bit error rate and packet loss rate, to make them meet the corresponding standards and ensure the performance of transceivers.
Optical Performance Testing
Test the transceivers' eye diagram situation, receiving sensitivity, extinction ratio, wavelength, light-emitting, light-receiving, current and voltage, to ensure the signal quality, stability and reliability of the transmission.
End Face Testing
Check the end face of the transceivers and keep them clean for more stable data transmission, better performance, and durability.
Various Switch Tests
Every module is quality tested for compatibility in the multi-brand switches environment, guaranteeing flawless operations.
