Difference Between 100G-QSFP-PSM4, 100G-QSFP-SR4 and 100G-QSFP-LR4
No Commentsby www.fiber-mart.com QSFP28 fiber optic transceiver is becoming the preferred solution for 100G network. It has the same outside looking as the 40G QSFP+ transceiver. But it has a 4*25G electrical interfaces which can transmit optical signals up to 100G. The part numbers of the QSFP28 transceivers are usually market as 100G-QSFP-xx. [ Continue reading…]
MTP Conversion Cable and Its Usage
No Commentsby www.fiber-mart.com 12-fiber MTP and 24-fiber MTP cables are widely used in 40G and 100G high density cabling. However, in many cases, not all the fibers are used. For instance, to connect a 40G-SR4 QSFP+ module, we usually use a 12-fiber MTP cable with only 8 fibers in use. If [ Continue reading…]
Understanding Optical Attenuators
No Commentsby www.fiber-mart.com Optical attenuators are used to reduce the power level of optical signal, either in free space or in an optical fiber. They are often used in optical communication systems where the optical signal is too strong and needs to be reduced, in which the attenuation, also called transmission loss, [ Continue reading…]
