Details:CWDM SFP is based on the SFP form factor which is a MSA standard build. The max speed of this product is 1.25G and they are also available as 2.5G 4G and of course the popular 10G CWDM SFP+.Solid-Optics always uses the part names of the Vendor for which it is compatible, so for Cisco we are using the original name including the extra parameters. Cisco original naming is CWDM-SFP-1550-DOM= we are adding the power budget (24dB) and make a clear distinction that it is a Solid-Optics product by adding "–SO" at the end. The complete part name is CWDM-SFP-1550-DOM-24dB-SO.All CWDM optics come with DOM/DDM which stands for "Digital optical monitoring" or "Digital Diagnostic Monitoring" which will enable you to measure in real time, the temperature, Voltage Tx laser output and Rx laser input.We offer 4 different versions of power budget: 24dB, 32dB, 37dB and 41dB. The 24dB CWDM SFP can reach around 80km depending on the nanometer, MUX quality and fiber quality. Because the attenuation on the lower bands (<1470) is higher, we mention 50km on the label. The 32dB can reach around 120km. The 37dB can reach around 150km. The strongest version is the 41dB which can reach around 200km, to reach this you will need our ULTRA-MUX and the attenuation on the fiber should be within specs. These can be connected to each other without the need for a mux.Youthton can make the SFP CWDM compatible with every brand. A lot of brands have vendor locking and only with the proper coding. Youthton is specialized in this rebranding or recoding. We have more the 20 different Switches and Routers in our test lab to test the coding.
