Optical transceiver module 200G QSFP56 SR4 YOC 3M 200G QSFP56 SR4 To 2x100G PAM4 Modulation And DDM Support

 200G QSFP56 SR4 YOC 3M Product Overview

The 200G QSFP56 SR4 to 2xQSFP56 SR2 Active Optical Cable (AOC) is a high-performance breakout solution designed for next-generation data centers and high-speed networking environments. It efficiently splits a single 200G port into two independent 100G channels, offering flexibility and scalability for modern network architectures. This optical transceiver module integrates advanced VCSEL and photodiode arrays to ensure reliable, low-power, and high-bandwidth connectivity over multimode fiber.

 200G QSFP56 SR4 YOC 3M Key Features

• Breakout design: One 200G QSFP56 SR4 to two 100G QSFP56 SR2 connectors
• PAM4 modulation supporting up to 53.125 Gbps per channel
• Integrated 850 nm VCSEL transmitter and PIN photodiode receiver arrays
• Digital Diagnostic Monitoring (DDM) for real-time performance tracking
• Hot-pluggable with low power consumption: <4W (200G end), <3W (100G end)
• Compliant with RoHS 2.0 and industry standards

 200G QSFP56 SR4 YOC 3MTechnology & Standards

This optical module complies with IEEE 802.3cd, InfiniBand HDR, SFF-8679, and CMIS 4.0 / SFF-8636 specifications. It uses PAM4 modulation technology to achieve high data rates with improved signal integrity and lower power consumption compared to NRZ modulation.

Working Principle

The AOC converts electrical signals into optical signals using VCSEL arrays at the transmitter end. The optical signals are transmitted over multimode fiber and converted back to electrical signals at the receiver end via photodiode arrays. The breakout functionality allows one 200G port to drive two separate 100G links, providing flexible connectivity options.
