  • Product description: MMA1L30-CR 100GbE QSFP28 CWDM4 Transceiver Product Specifications


NVIDIA® MMA1L30-CM transceiver is a single mode 4- channel (CWDM4), QSFP28 optical transceiver, designed for use in 100 Gigabit Ethernet (GbE) links on up to 2km of single mode fiber. It is also qualified for use in InfiniBand EDR end-to-end systems.

Two options of the transceiver are available - Option 1 and Option2, with identical functionality but with minor mechanical differences. The module (in both options) converts 4 input channels of 25 Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single fiber, using a nominal wavelength of 1310nm, for 100Gb/s optical transmission. Reversely on the receiver side, the 100Gb/s optical input is demultiplexed into 4 channels of CWDM optical signals and then converted to 4 output channels of electrical data.

The MMA1L30-CM has selectable retiming as specified in the SFF-8636 MSA. The transceiver can therefore be used in both 40 and 100 GbE applications.

Digital diagnostic monitoring functions for temperature, supply voltage, and optical power are available via the two-wire (I2C) management interface, as specified by the QSFP28 MSA.

The optical connector is a duplex LC/UPC (un-angled) connector intended for a pair of single mode fibers.

Rigorous production testing ensures the best out-of-the-box installation experience, performance, and durability.
