Tips for the 40G QSFP + SR4 optical module interconnection
Posted on Jul 11, 2017 by cozlink.com
Today, 40G network has gradually developed into a backbone network for long-distance network transmission applications. And the 40G QSFP+ SR4 optical module is widely used in 40G short-range network transmission. In general, 40G QSFP + SR4 optical module can work in the 850nm wavelength environment,can support up to 150 meters of 40G fiber optic network transmission in the OM4 multi-mode. QSFP + SR4 optical module uses MTP / MPO dual-channel network transmission interface design, just with a different connection products, can ensure that in a variety of applications in a variety of ways to QSFP + SR4 optical modules connected with other devices. In addition, because 40G network cabling is more difficult than 10G, always need more fiber jumpers and spacing, the following will introduce several high-density QSFP + SR4 optical module wiring methods.40G QSFP + SR4 optical module 40G to 40G transmission applicationsIn the 40G fiber network environment for 40G to 40G transmission.
