Introduction
NVIDIA® MMS1V70-CM transceiver is a single
mode 1-lane (DR1), QSFP28 optical transceiver,
designed for use in 100 Gigabit Ethernet (GbE)
links on up to 500m of single mode fiber.
The transceiver converts 4 input channels of
25Gb/s NRZ electrical data to a single optical
channel of 100Gb/s PAM4 optical signals over a
single fiber, using a nominal wavelength of
1310nm, and vice versa for the receive path.
The MMS1V70-CM main application is to
converge between legacy 100GbE NRZ systems
and the emerging 400GbE PAM4 systems. Four
different MMS1V70-CM transceivers can be
connected to a single 400GbE QSFP-DD
MMS1V00-WM DR4 transceiver over a single
mode splitter cable.
It is compliant with the QSFP28 MSA, IEEE
802.3bm CAUI-4. Digital diagnostic functions are
available via the I2C interface, as specified by
the QSFP28 MSA.
Rigorous production testing ensures the best
out-of-the-box installation experience,
performance, and durability.
