Data rate 155Mbps to 2.5Gbps per channel
12 parallel channels, total 30Gbps capacity
Differential CML (Current-Mode Logic) interface
Link length up to 300m (with 500MHz km fiber)
The MFT62340 and MFR62340 is a very high speed
transmitter and receiver pair for parallel fiber
applications. This pair, together with a multimode
parallel fiber ribbon cable, constitute a complete
parallel fiber link. The link provides high-speed
interconnects for use within and between large
capacity switches, routers and data transport
equipment. The transmitter and receiver have a
differential CML interface and support MPO/MTP
and MPX fiber connectors. An EMI shield is available
for the MPO/MTP connector for use in front panel
applications.
