TOSA) with optical fiber interface component (the Receiver Optical Subassembly of low cost；ROSA).
The optical fiber interface component of prior art is assembled by two-part construction shell and bonnet, and production cost is high, has in fact
Necessity improves.The optical signal of fiber-optic transfer enters into the approach on detector chip mainly two kinds of forms: direct-coupling,
Lens Coupling, during direct-coupling, optical fiber is directly coupled and aligned with chip, and the responsiveness index of chip is poor.Lens Coupling is
Between optical fiber and chip, add the combination of some simple lenses or poly-lens, utilize Lens Coupling can obtain than direct coupling
Close higher coupling efficiency.It is commonly used in the optical fiber interface component coupled with butterfly device, uses outside self-focusing glass lens
Overlap the mode of gold-plated sleeve pipe, relatively costly；Lens material is that glass, intensity and hardness are low, easily damaged.It addition, connect at optical fiber
When mouth assembly is connected with the optical fiber tube of butterfly photo-detector shell, owing to the weldability of gold-plated sleeve pipe is poor, connect frequently with gluing,
Connect instability, make the coupling focal length of glass lens change, thus affect properties of product stability.
