Mellanox MMA2P00-AS 25GbE SFP28 SR Optical Transceiver for High-Speed Networking
1. Product Overview
The Mellanox MMA2P00-AS is a high-performance SFP28 optical transceiver module engineered for 25 Gigabit Ethernet applications. This fiber optic transceiver operates over multi-mode fiber (MMF) using 850nm wavelength technology, delivering reliable connectivity for data centers and enterprise networks. Designed for efficiency and compatibility, this optical transceiver supports both 25GbE and 10GbE rates with exceptional signal integrity.
2. Key Characteristics
- Dual-rate support: 25GbE and 10GbE operation
- Programmable transmitter equalization and receiver emphasis
- Extended reach: 100m on OM4 MMF, 70m on OM3 multi-mode fiber
- Hot-pluggable SFP28 form factor with LC duplex interface
- Low power design: 0.7W typical with retiming enabled
- Class 1 laser product ensuring eye safety
- Compliant with RoHS and industry standards
3. Technology & Standards Compliance
This SFP28 optical transceiver complies with IEEE 802.3bm, SFF-8402, and SFF-8472 standards. It features advanced DSP technology with selectable retiming capabilities for both transmit and receive paths. The module supports Digital Diagnostic Monitoring (DDM) for real-time performance tracking.
4. Operational Principle
The transceiver converts electrical signals to optical signals using an 850nm VCSEL laser source. These optical signals transmit through multi-mode fiber optic cables, then are converted back to electrical signals at the receiving end. Built-in signal conditioning features maintain integrity across various fiber distances and conditions.
5. Application Scenarios
Ideal for data center interconnects, high-performance computing clusters, enterprise network upgrades, and storage area networks. Compatible with switches, routers, and network interface cards from major vendors that support SFP28 form factor and 25GbE standards.
