• Supports 100GBASE-LR4/ER4
• Supports OTU4 28 Gbps operation for OTL4.4
• Self adaptive receive equalization
• High resolution Rx eye scan - iSCAN
• Loss of Protocol Lock detection
• Test pattern generation and checking
• Monitor clock output
Description
The 100GBASE-LR4/ER4 long reach fiber optic PMD uses four 25 Gbps
wavelengths. To interface with system ASICs with 10G I/Os, a gearbox function
is required. Next generation 100G modules are designed to allow the gearbox
function to be placed on the line card, rather than inside the module. This allows
the creation of denser, lower power modules by reducing the number of module
pins and removing the gearbox function from the module and replacing it with
two iPHY IN012525s.
Next generation 100G modules also support OTU OTL4.4 by running the
interfaces 12% faster (11.2 and 28 Gbps). The iPHY IN012525 also supports this
rate (two discrete rates are supported). In this document although interfaces
may be referred to by their ethernet rates, support for OTL4.4 rates is implicit.
