MMA1B00-E100 Mellanox Server Transceiver

High-Density QSFP28 100GbE SR Multimode Optical Transceiver for Leaf/Spine Fabrics with the MMA1B00-E100

The MMA1B00-E100 is a Mellanox/NVIDIA QSFP28 SR optical transceiver engineered for 100GbE short-reach connectivity in modern data centre switching, HPC, and AI cluster networks. Designed for multimode fibre environments, the MMA1B00-E100 provides a practical optical path for high-throughput east-west traffic where rack-scale cabling discipline and predictable link budgets are required.

Architecturally, the MMA1B00-E100 supports 100GbE class bandwidth using VCSEL-based 850 nm parallel optics and an MTP/MPO-12 interface, aligning with dense switch front panels and high-port-count NIC uplinks. By focusing on SR multimode reach up to 100 m, the module targets top-of-rack to end-of-row and leaf-to-spine interconnects while keeping power, physical layer complexity, and optics management appropriate for short-reach domains. The MMA1B00-E100 integrates cleanly into PCIe-attached 100GbE NIC deployments by providing deterministic optical performance for latency-sensitive fabrics and high fan-in switching tiers.

Why Choose the MMA1B00-E100?

The MMA1B00-E100 is selected when enterprises need predictable 100GbE density without overbuilding the optical layer for short links. It enables scalable port expansion for leaf/spine architectures and cluster uplinks while maintaining operational consistency through standards-based interoperability. The MMA1B00-E100 supports straightforward growth from single-rack acceleration nodes to multi-rack fabrics with repeatable cabling and transceiver logistics.

Mellanox designs optics to match data centre reliability expectations, focusing on signal integrity, compliance alignment, and stable operation in high-density switching environments. With IEEE 802.3 and SFF-8665 adherence and RoHS compliance, the MMA1B00-E100 fits established enterprise qualification processes and modern infrastructure standards.

Key Applications:

• 100GbE leaf/spine interconnects over multimode fibre
• HPC and AI cluster fabric uplinks
• NIC-to-switch 100GbE short-reach links
