Features

Description

•

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.
