General Description
The CFP-40GBASE-ER4 is a 40Gb/s transceiver module for optical communication
applications compliant to 40GBASE-ER4 of the IEEE P802.3ba standard. The module
converts 4 inputs channels of 10Gb/s electrical data to 4 CWDM optical signals and
then multiplexes them into a single channel for 40Gb/s optical transmission.
Reversely on the receiver side, the module de-multiplexes a 40Gb/s optical input into
4 CWDM channels of optical signals and then converts them to electrical data for 4
output channels.
The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm
as members of the CWDM wavelength grid defined in ITU-T G694.2. For SMF
applications, the transceiver module has an operating range up to 40km SMF.
The CFP-40GBASE-ER4 is designed with form factor, optical/electrical connection and
MDIO interface according to the CFP Multi-Source Agreement (MSA). The innovative
design has all the fibers inside the CFP package configured without any splicing or
non-permanent connector. Also, fiber routines are neatly organized and fixed inside a
stainless steel container. For mechanical and environmental reliability, the WDM
sections are aligned and secured to the container by laser welder, and then aligned
and affixed with each high power CWDM laser or APD/TIA TO to form an integrated
structure of TOSA or ROSA.
Functional Description
The CFP-40GBASE-ER4 contains a duplex Straight LC connector for the optical interface
and a 148-pin connector for the electrical interface. The chart in section 3 shows the
functional block diagram of the CFP-40GBASE-ER4 CFP Transceiver.
