Cudy Single Mode 1.25G Lc Bi-Directional Sfp 20KM
Cudy's CD-SFP-SMB is your answer for efficient and cost-effective single-mode fibre deployments! These bi-directional modules redefine connectivity standards with a powerful design optimised for 1.25 Gbps transmission over distances of up to 20km. The CD-SFP-SMB modules are sold as a pair and feature a smart SFP package with LC connectors, ensuring cross-vendor compatibility. What distinguishes them is their novel application of bi-directional technology, which enables duplex transmission on a single fibre by utilising two distinct wavelengths for TX and RX on the same optical strand. This not only improves performance but also significantly lowers installation costs. Choose between the SM100GSB-20A with a 1310nm FP laser and a 1550nm PIN photodetector or the SM100GSB-20B with a 1550nm DFB laser and a 1310nm PIN photodetector to meet your specific requirements. These modules provide dependable performance because they are powered by a single +3.3V power supply and have an LVPECL-compatible data input/output interface. The CD-SFP-SMB provides a strong and secure connection thanks to its low EMI and excellent ESD protection. These modules prioritise environmental sustainability while adhering to RoHS and SFF8472 standards.
