CUDY SINGLE MODE 1.25G LC BI-DIRECTIONAL SFP 20KM | SM100GSB-20AB

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.FEATURES:SFP package with LC connector SM100GSB-20A: 1310nm FP Laser and 1550nm PIN photodetectorSM100GSB-20B: 1550nm DFB Laser and 1310nm PIN photodetectorUp to 20 km transmission on SMF 3.3V single power supplyLVPECL-compatible data input/output interfaceLow EMI and excellent ESD protectionCompatible with RoHSCompatible with SFF8472SPECIFICATIONS:Ethernet Channel Speed: 1.25 GB/sFibre Channel Speed: 1.06 Gb/sForm Factor: SFP (BiDi)Mode: Single ModeSupported Distance: 20kmWavelength: 1310nm / 1550nmOptical Eye Diagram: IEEE 802.3z and ANSI Fibre Channel CompatibleInput Differential Impendence (Min) (Max): 90, 110 OhmData Input Swing Differential (Min) (Max): 500, 2400 mVOutput differential impendence (Typ): 100 OhmData Input Swing Differential (Min) (Max): 370, 2000 mVSupply Voltage (Min) (Max): 3.15, 3.45 VOperating Case Temperature (Min) (Max): 0, 70 ℃Voltage: 3-15 ~ 3.45 VBias Current: 10 ~ 80 mATx Power: -9 ~ -3 dBmRx Power: -26~-3 dBmWHAT’S IN THE BOX:Cudy 1.25Gbps BIDI SFP Optical Transceiver 20Km DDM x1Installation Guide x1N.B.: Your payment is encrypted and handled through a secure gateway; we never access or retain card details.
