These bi-directional modules redefine connectivity standards with a powerful design optimised for 1.25 Gbps transmission over distances of up to 20km.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eChoose 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.\u003c\/p\u003e\n\u003cp\u003eThese 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.\u003c\/p\u003e\n\u003ch3 style=\"color: #2c3e50; border-bottom: 2px solid #eee; padding-bottom: 5px;
