Description

The NVIDIA LinkX MMS1V70-CM is a single-mode, single-lane (DR1) QSFP28 optical transceiver for 100GbE links over single-mode fibre. It is aimed at data centre links up to 500m, and in particular at breakout and convergence between 100GbE NRZ QSFP28 switches and 400GbE PAM4 QSFP-DD DR4 switches.

The module converts a 4x25Gb/s NRZ electrical interface (CAUI-4) into one 100Gb/s PAM4 optical channel at a nominal 1310nm wavelength, with a signalling rate of 53.125 GBd. It uses a duplex LC-LC connector and supports an operating distance of 2m to 500m. Maximum power dissipation is 4W from a single 3.3V supply, falling to 1.5W in low power mode, and the case operating temperature range is 0 to 70 C.

Four MMS1V70-CM modules on an MSN2700 switch can connect to a single MMS1V00-WM DR4 transceiver on an MSN4700 switch through a single-mode splitter cable. The module is QSFP28 MSA compliant and fits SFF-8665 compliant QSFP28 and QSFP56 ports.

Features

- Bridges legacy 100GbE NRZ systems with emerging 400GbE PAM4 systems
- Four modules can connect to one 400GbE QSFP-DD MMS1V00-WM DR4 transceiver via a single-mode splitter cable
- Programmable Tx input equalisation, Rx output amplitude and Rx output pre-emphasis
- Tx/Rx CDR control, enabled by default for 100GbE and able to be disabled for 40G operation
- Digital diagnostics for Rx/Tx optical power, Tx bias current, supply voltage and case temperature, with warning and alarm thresholds
- Tx/Rx LOS, LOL and Tx fault indication via IntL
- Hot pluggable and RoHS compliant

FAQs

Q: What is the maximum reach of this transceiver?
A: It supports links from 2m up to 500m over single-mode fibre using a duplex LC-LC connection.

Q: Can it connect a 100GbE switch to a 400GbE switch?
A: Yes. Four MMS1V70-CM modules on an MSN2700 switch can connect to a single MMS1V00-WM QSFP-DD DR4 transceiver on an MSN4700 switch via a single-mode splitter cable.

Q: What power does it draw?
A: It runs from a single 3.3V supply with a maximum power dissipation of 4W, dropping to 1.5W in low power mode.

Q: Which ports does it fit?
A: It fits SFF-8665 compliant QSFP28 and QSFP56 ports and complies with the QSFP28 MSA and IEEE 802.3bm CAUI-4.

Q: Does it support digital diagnostics?
A: Yes. It provides per-lane Rx/Tx optical power and Tx bias current, plus supply voltage and case temperature monitoring, with warning and alarm thresholds via the SFF-8636 I2C interface.
