Fiber Breakout
Fiber Breakout for UFM6 QSFP+ Ports
The QSFP+ transceivers used on the UFM6 are parallel single mode transceivers that have four parallel 10-Gbps lanes. To provide access to these individual 10-Gbps channels, Juniper Networks has adopted GigaLight's fiber breakout solution, which consists of a fiber cassette and rack.
The QSFP+ transceiver connects to the GigaLight fiber cassette through a single cable (consisting of multiple single-mode fibers), which is split within the cassette into individual 10-Gbps fiber pairs that are accessible from the cassette faceplate (Figure 1). The cassette can be mounted into a GigaLight 1U GigaC Rack (holds 12 cassettes).

Alternatively, you can provide access to the individual 10-Gbps channels through a fiber breakout cable directly, without using the GigaLight fiber cassette solution. The breakout cable connects to the QSFP+ transceiver at one end and provides four LC/UPC connectors at the other end for access to the four individual 10-Gbps channels.
The components for both of these options are listed in Fiber Breakout Components.
