MMA1B00-B150D 40GbE QSFP+ SR4 Optical Transceiver

1. Product Overview

The Mellanox® MMA1B00-B150D is a high-performance, QSFP+ form factor, optical transceiver module engineered for 40 Gigabit Ethernet applications. This 4-channel VCSEL-based module delivers reliable data transmission at 4x10.3125 Gb/s per channel over parallel multi-mode fiber (MMF), achieving reaches of up to 150 meters on OM4 fiber. It is an essential component for upgrading network infrastructure, offering a perfect blend of high bandwidth, low power consumption, and robust diagnostic capabilities, making it superior to a simple passive fiber cable solution.

2. Key Characteristics

• Data rate: 40GbE (4x10.3125 Gb/s)
• Reach: Up to 150m on OM4 MMF, 100m on OM3 MMF
• Low power dissipation: 1.3W typical
• Hot-pluggable QSFP+ form factor
• Digital Diagnostic Monitoring (DDM/DOM) interface
• Class 1 Laser Product compliant (IEC 60825-1, FDA)
• RoHS compliant
• BER better than 10^-15

3. Core Technology & Standards

This transceiver utilizes advanced 850nm VCSEL (Vertical Cavity Surface Emitting Laser) technology and is fully compliant with IEEE 802.3ba 40GBASE-SR4. It adheres to the SFF-8436 and SFF-8636 specifications for mechanical form factor, management interface, and digital diagnostics, ensuring broad interoperability with compliant QSFP+ switch ports. This active Optical Fiber Cable component is designed for high-speed data center networks.

4. Working Principle

The electrical interface receives four lanes of 10.3125 Gb/s data from the host switch. The integrated driver chips modulate four 850nm VCSEL lasers, converting the electrical signals into optical signals. These signals are transmitted through an MPO connector into a parallel multi-mode Optical Fiber Cable. At the receiving end, a matching transceiver uses photodiodes to convert the incoming optical signals back into electrical data streams for the host system. Integrated circuitry provides programmable input equalization and output emphasis to ensure signal integrity.

5. Application Scenarios

• 40GbE switch-to-switch connections in data centers
• High-density aggregation links
• Connecting servers with 40GbE interfaces to top-of-rack switches
• Storage area network (SAN) and network-attached storage (NAS) connectivity
• High-performance computing (HPC) clusters

9. Frequently Asked Questions

Q: What type of fiber cable is required for this transceiver?
A: It requires a parallel multi-mode fiber (MMF) cable with MPO/MTP® connectors, specifically OM3 or OM4 grade for the advertised reach. It is not a passive fiber cable itself but is used with one.

Q: Is this module compatible with my brand-X switch?
A: While designed to the multi-vendor SFF-8436 standard, compatibility should be verified with your switch manufacturer's compatibility matrix. We can provide guidance on interoperability.

Q: Does it support Digital Diagnostic Monitoring (DDM)?
A: Yes, it provides full DDM functionality for monitoring voltage, temperature, TX/RX optical power, and laser bias current via the I²C interface.

10. Precautions

• Ensure the host equipment's QSFP+ port is compliant with SFF-8436.
• Always use an approved dust cap when the transceiver is not connected to a fiber cable.
• Operate and store within the specified temperature and humidity ranges.
• This is a Class 1 laser product that is safe under all normal operating conditions. Do not disassemble.
• Handle the MPO connector and associated Optical Fiber Cable with care to avoid contamination or damage to the end faces.
