12-Fiber Ribbon Breakout Cables with MPO-to-LC Duplex Connectors
You can use 12-ber 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-ber
ribbon ber-opc 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 other end.
Figure 22 on page 59 shows an example of a typical 12-ber ribbon breakout cable with MPO-to-LC
duplex connectors (depending on the manufacturer, your cable might look dierent).
