Descriptions of 100G QSFP28 module
The Sopto 100GBASE-ER4 Lite & OTU4 40km QSFP28 optical transceiver
(SPT-QSFP28-ER4) is designed for use in 100-Gigabit Ethernet and
OTN links up to 30km without FEC or 40km with FEC on Single Mode
Fiber (SMF). It is compliant with the QSFP28 MSA, 4WDM-40 MSA, IEEE
802.3ba 100GBASE-ER4 and IEEE 802.3bm CAUI-4, and OTU4 standards.
Digital diagnostics functions are available via an I2C interface,
as specified by the QSFP28 MSA. It converts 4 input channels of
27.95Gb/s electrical data to 4 channels of LAN-WDM optical signals
and then multiplexes them into a single channel for 111.8Gb/s
optical transmission. Reversely on the receiver side, the module
de-multiplexes a 111.8Gb/s optical input into 4 channels of LAN-WDM
optical signals and then converts them to 4 output channels of
electrical data. The central wavelengths of the 4 LAN-WDM channels
are 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm as members of the
LAN-WDM wavelength grid defined in IEEE 802.3ba.
