Brocade FC16-64 Port Blade QuickStart Guide (Supporting DCX 8510-4 and DCX 8510-8 with Fabric OS 7.3.0 and above) - Manual (Page 6)

QSFP transceiver
The FC16-64 port blade supports only Quad-SFP (QSFP) ports where a single MTP connector
supports up to four channels or ports. Thus, QSFP allows for simplified cable management and, at the
same time, supports high density SAN solutions. The QSFP transceivers differ from standard SFP+ or
mSFP transceivers. Cables with MTP/MPO connectors are required to use the QSFP transceivers.
The cables can be identified by the special connector at the QSFP end and the cables are of different
diameter (2.5×6.4 mm)than the standard LC-LC cables.
CAUTION
DO not use the standard SFP+ or mSFP optical transceivers with the FC16-64 port blade. They
do not fit correctly and can cause damage to the ports, cage connectors, and transceivers. Do
not force standard LC or mSFP connectors into the QSFP transceivers. This could result in
damage to both the connector and the cable.
The following figure shows the QSFP transceiver and the connector.
