2.YouthtonApplication of 40G LR4§40G LR4 QSFP+ transceivers are most commonly deployed between data-center or IXP sites with single mode fiber.§40GBASE-SR4 QSFP+ transceivers are used in data centers to interconnect two Ethernet switches with 12 lane ribbon OM3/OM4 cables.Fiber Type and Connector§40G LR4 QSFP+ transceivers support link lengths of up to 10 kilometers over a standard pair of G.652 single-mode fiber with duplex LC connectors.§40GBASE-SR4 QSFP+ transceivers are generally enable high-bandwidth 40G optical links over 12-fiber parallel fiber terminated withMPO/MTPmultifiber connectors.Wavelength (nm)§40G LR4 QSFP+ (Multiplexing and demultiplexing of the four wavelengths are managed within the device): 1271 nm, 1291 nm, 1311 nm, 1331 nm§40GBASE-SR4 QSFP+: 4 x 850 nmTransmission Distance§40GBASE-LR4 QSFP+ (CWDM)– 10 km on single-mode– 4λ x 10G 1300 nm region§40GBASE-SR4 QSFP+ (parallel optics)– 100 m on OM3–10G on 4 fibers per direction– 150 m on OM4 –10G on 4 fibers per directionObviously, the 40G QSFP LR4 is designed for long transmission used with single-mode fiber while 40G QSFP SR4 is for short distance with OM3/OM4. And "4" here means four lanes. Additionally, they are in different wavelengths and with different connectors. When they used in actual network, they are used different technology.Ok, the article will be end here as todays topic is simple. I hope that this post will give you some help and of course due to the limited knowledge of the author, there are some inevitable errors and omissions existing in |
