CFP Dual 40GBASE-SR4 / OTU3 Parallel Optical Module

pictureDesigned to support the IEEE 40GBASE-SR4 link specification; the newly developed F-tone Dual 40G CFP transceiver offers 2 independent 40G Ethernet links in one CFP slot. The F-tone CFP transceiver has two MPO ports which connect to industry standard 12-fiber multi-mode fiber cable. Both MPO ports will inter-operate with equipment using 40GBASE-SR4 QSFP transceivers. The Dual 40GE CFP transceiver doesn’t require any special hardware and plugs into the same slot as 40GBASE-LR4, 100GBASE-SR10 and 100GBASE-LR4 CFP modules. So with only software changes, a CFP slot can change between two 40GE ports into a single 100GE port.

The new F-tone Dual 40G Ethernet transceiver, combined with the F-tone 100G Ethernet CFP transceiver, opens up new interconnect possibilities in the data center.

F-tone hot-pluggable CFP modules offer 2 x 4 transmit and 2 x 4 receive asynchronous channels operating at up to 11.2 Gbps per channel. All transmit and receive lanes are capable of 11.2 Gbps operation for an aggregate bandwidth of >44 Gbps over 100 meters of high-bandwidth multi-mode parallel optical fiber cables. The transmitter side of each 40G MPO port consists of an array of 4 850nm VCSELs (Vertical Cavity Surface Emitting Lasers) and associated circuitry, which converts 4 parallel electrical data inputs to 4 parallel optical data output signals. The receiver side converts 4 parallel optical signals into 4 parallel electrical signals through an array of 4 PIN photodiodes, TIA / LAs and associated circuitry.

The CFP modules have been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference using F-tone’ next generation, F-tone packaging technology. The modules offer very high functionality and feature integration, accessible via an MDIO interface.
