Hyoptic‘s 40GBASE-LR4 QSFP+ Optical Transceiver single fiber solution

40GBASE-LR4 QSFP+ Optical Transceiver can achieve single-fiber transmission through Hyoptic fiber optic circulators, The center wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm. Hyoptic‘s circulators range from 1270-1340nm, and the insertion loss can be controlled below 0.8nm, which can provide a good solution for single-fiber transmission.
