12-Fiber Ribbon Breakout Cables with MPO-to-LC Duplex Connectors
You can use 12-ribbon breakout cables with MPO-to-LC duplex connectors to connect a QSFP+
transceiver to four separate SFP+ transceivers—for example, 4x10GBASE-LR-to-10GBASE-LR or
4x10GBASE-SR-to-10GBASE-SR SFP+ transceivers. The breakout cable is constructed out of a 12-fiber
ribbon fiber-optic cable. The ribbon cable splits from a single cable with a socket MPO connector on one
end, into four cable pairs with four LC duplex connectors on the opposite end.
Figure 20 on page 62
shows an example of a typical 12-ribbon breakout cable with MPO-to-LC duplex
connectors (depending on the manufacture, your cable may look different).
