QSFP+ optical modules bridge compatibility gap

QSFP+ optical modules bridge compatibility gap

Said to enable more efficient switching and greater bandwidth in data centers, the AFBR-79EIDZ pluggable parallel optical QSFP+ eSR4 transceiver module is described as the first module that can address both 40 Gigabit and 10 Gigabit Ethernet applications with a verified link distance of 400 meters. This gives data center operators the flexibility to reuse the current 10G wired infrastructure when upgrading to 40G, for major cost savings.

The AFBR-79EIDZ modules integrate four 10G lanes in each direction to increase bandwidth on a line card. The module can allow 176 10G-channels with QSFP+, instead of the 48 SFP+ channels available today. They use reliable 850-nm vertical-cavity surface-emitting laser (VCSEL) technology and PIN detector technology. ($800 ea/10 — available now.)
