Description

The NVIDIA LinkX MFA1A00-E030 is a 30m VCSEL-based QSFP28 active optical cable built for 100Gb/s InfiniBand EDR links. It runs over multimode fibre with a hot-pluggable QSFP28 connector on each end and an aqua LSZH (Low Smoke Zero Halogen) jacket. It suits very high-speed InfiniBand HPC and data centre interconnects, particularly rack-to-rack and longer runs where passive copper is too short.

The cable carries 4 x 25G NRZ channels over multimode fibre, for up to 100Gb/s in total, with a bit error rate better than 1E-15. The host interface is SFF-8665 compliant QSFP28, with SFF-8636 compliant I2C management. Power is drawn from the host port at 3.3V, with typical dissipation of 2.2W per end with retiming on and 1.5W per end with retiming off. The cable diameter is 3 mm with a 30 mm minimum bend radius, and the operating case temperature range is 0 to 70 C. No licence or subscription is required.

It is intended for InfiniBand EDR 100Gb/s QSFP28 ports, such as ConnectX-5 adapters and EDR switches. Digital diagnostic monitoring requires firmware 32.20.124 or higher.

Enquire with XS Network Tech for new or used pricing and availability.

Features

FAQs

Q: Does this cable need a licence or subscription?
A: No. It is a passive-managed optical cable with no licence or subscription requirement.

Q: How much power does it draw?
A: It draws power from the host QSFP28 port on a single 3.3V supply. Dissipation is 2.2W typical per end with retiming on and 1.5W typical per end with retiming off.

Q: What ports and devices does it work with?
A: It is designed for InfiniBand EDR 100Gb/s QSFP28 ports, such as ConnectX-5 adapters and EDR switches. MFA1A00-E030 is listed as compatible in the ConnectX-5 firmware release notes.

Q: Can I read optical diagnostics from the cable?
A: Yes. It supports digital diagnostic monitoring of temperature, voltage, laser bias current and Tx and Rx optical power. This requires firmware 32.20.124 or higher.

Q: How does this cable differ from other MFA1A00 lengths?
A: This SKU is the 30m InfiniBand EDR version with an LSZH jacket. Other MFA1A00 part numbers use the same technology in different lengths.
