With fiber airtight Components> Purpose Chuxing provide airtight performance fiber optic products to customers, used in hermetically sealed devices, optical filters, 1 × 2 WSS, 1 × 9 WSS products. Product good adhesion, high tensile strength, good weldability, welding up to 220 ℃ temperature welding, metalization length: 5-40mm. Airtight packaging structure is mainly used for welding various active and passive optical devices, grating sensor type welding applications. > Performance indicators single, multi-core, four-core, eight-core, twelve core, forty-eight core insertion loss (dB) ≤0.3 coating thickness 3 ~ 4μm (standard) or 1 ~ 10μm (customer request) partial loss-dependent loss ( dB) ≤0.2 tightness (atm-cc / sec) ≤1.0E-8 temperature stability (-40-100 ℃) (dB) <0.15 Soldering Temperature (℃) ≤220 ℃ Fiber Type SMF-28e or customer specified work storage temperature (℃) -40 ~ + 85 ℃ middle airtight Components> Product schematic> Features of this product with a proven chemical plating process preceding the desired fiber length, fiber cladding outside and then plated with nickel in a nickel layer on the surface gold plated; localized metallized optical fiber so as to achieve the purpose. Good weldability, can withstand 280 ℃ welding solder 30 seconds, good adhesion, high tensile strength (hot solder process Rally Secretary Chu Xinggong reach 10N). The total thickness of the coating: 3-4um, gold layer thickness ≮0.1um.
