Within racks and across adjacent racks QSFP+ switches

The QSFP+ electrical loopback adds another solution for test engineers in both manufacturing and development environments,” said Mike Reiling, key account manager. “The addition of the QSFP+ to our XFP, SFP and SFP+ electrical loopbacks has strengthened our commitment to economical board testing as well host-board electrical-edge connector and cage. The hot-pluggable transceiver integrates 4 transmit and 4 receive channels. Molex's QSFP+ transceiver can replace up to 4 standard SFP+ transceivers. The result is greater port density and overall system cost savings over traditional SFP+ products. Molex's QSFP+ cable assemblies are designed to accommodate stacked and ganged connector configurations in extremely high-density requirements QSFP+ Passive Electrical Loopback is used for testing QSFP+ transceiver ports in board level test. The electrical loopback provides a cost effective low loss method for QSFP+ port testing. The  is packaged in a standard housing compatible with all QSFP+ ports. Transmit data from the host is electrically routed,
