1260 1350nm C Lens Fiber Collimator Pigtail Low Insertion Loss 15mm Working Distance Ceramic Pigtail Collimator for Optical Module
Product Overview
This product is a C-Lens ceramic pigtail collimator fiber optic assembly, operating in the wavelength range of 1260–1350 nm with a working distance of 15 mm.
Core Product Features
O-Band Operation Capability
Operating wavelengths cover 1260–1350 nm, suitable for O-band optical communication systems and internal optical path coupling applications within optical modules.
Low Insertion Loss Design
At a working distance of 10–15 mm, the insertion loss IL < 0.20 dB, effectively reducing optical path coupling loss and improving system transmission efficiency.
Stable Spot Output Performance
The reference spot size values are 260±3 μm at 3 mm, 278±3 μm at 10 mm, 310±5 μm at 20 mm, and 355±8 μm at 30 mm, with a spot ellipticity > 96%.
High Return Loss and Low Wavelength Dependent Loss Return loss RL > 55 dB, wavelength dependent loss WDL < 0.15 dB, point accuracy ≤ 1.5°, contributing to improved optical path stability and coupling consistency.
Reliable Structure and Environmental Adaptability
Utilizes C-Lens lenses with a radius of curvature of 1.0 mm; outer diameter φ1.40 mm, length 3.80±0.1 mm, tail adhesive length 0.5–1.5 mm, and fiber length 400 mm. Operating temperature -20℃ to 85℃, storage temperature -40℃ to 85℃, meeting RoHS requirements.
