Generic Compatible 50GBASE-SR SFP56 850nm 100m Duplex LC/UPC MMF Transceiver Module
Overview
The Generic Compatible 50GBASE-SR SFP56 is an optical transceiver module designed for 50Gbps data transmission. It utilizes an 850nm VCSEL laser source and supports link lengths of up to 100 meters when used with OM4 multi-mode fiber (MMF). The module features a duplex LC/UPC optical interface and integrates a Semtech chip with a built-in CDR (Clock and Data Recovery) for both transmit and receive channels, operating with a maximum power consumption of 1.5W.
Key Features
- PAM4 Modulation Format: Utilizes pulse-amplitude modulation to support 53.125Gbps data rates over multi-mode fiber.
- Built-in Clock and Data Recovery (CDR): Incorporates TX and RX CDR for signal integrity, ensuring stable data transmission across the link.
- Low Power Consumption: Consumes 1.5W or less, minimizing thermal output during operation within networking equipment.
- Digital Diagnostics Monitoring (DDM/DOM): Supports real-time monitoring of transceiver parameters via a 2-wire serial interface for simplified link management.
- Standardized Form Factor: Compliant with SFP56 MSA, SFF-8402, SFF-8472, and SFF-8419 standards for broad equipment compatibility.
