Mellanox MMA2P00-AS 25GbE SR SFP28 Multi-Mode Fiber Optical Transceiver
1. Product Overview
The Mellanox MMA2P00-AS is a high-performance SFP28 optical transceiver designed for 25 Gigabit Ethernet applications. It supports data transmission over multi-mode fiber (MMF) using 850nm wavelength and is ideal for high-speed data center and enterprise networking environments. This optical transceiver ensures reliable performance with low power consumption and compliance with industry standards.
2. Key Features
- Selectable retiming for both transmitter and receiver
- Programmable receiver output emphasis and transmitter input equalizer
- Supports up to 100m on OM4 and 70m on OM3 multi-mode fiber
- Hot-pluggable SFP28 form factor
- Low power consumption: 0.7W typical with retiming
- Class 1 laser product compliant
- RoHS compliant and IEEE 802.3 standards compatible
3. Technology & Standards
The MMA2P00-AS optical transceiver complies with SFF-8402, SFF-8472, and IEEE 802.3bm standards. It supports both 25GbE and 10GbE rates with rate selection via CDR control. This fiber optic transceiver uses advanced DSP technology for signal integrity and error-free transmission.
4. Working Principle
The transceiver converts electrical signals into optical signals using a 850nm VCSEL laser. The signal is transmitted over multi-mode fiber and converted back to electrical signals at the receiving end. Built-in retiming and equalization features ensure minimal jitter and signal degradation.
5. Applications
Ideal for data centers, cloud infrastructure, high-performance computing, and enterprise networks. Suitable for use in switches, routers, and network interface cards supporting 25GbE and 10GbE Ethernet.
