MMA1L10-CR 100GbE QSFP28 LR4 Transceiver Product Specifications

Introduction

NVIDIA^® MMA1L10-CR is a 4-channel pluggable QSFP28 optical transceiver designed for 100 Gigabit Ethernet (GbE) links with up to 10 km reach on a single mode fiber. It is also qualified for use in InfiniBand EDR end-to-end systems.

This transceiver is compliant with the QSFP28 MSA, IEEE 802.3ba 100GBASE-LR4 and IEEE 802.3bm CAUI-4. Digital diagnostic functions are available via the I2C interface, as specified by the QSFP28 MSA.

The MMA1L10-CR module converts 4 input channels of 25 Gb/s electrical data to 4 channels of LAN WDM optical signals at 4 different wavelengths and multiplexes these signals into a single optical transmit signal. On the receiver side, the module de-multiplexes a 100Gb/s optical LAN WDM input into 4 optical signals and then converts these to 4 electrical differential output signals. This transceiver has selectable retiming as specified in the QSFP28 MSA and can therefore be used in both 40 GbE 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 ‎[1].

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.
