400G QSFP-DD SR8 Optical Transceiver Module — High-Speed, Low Power, MSA Compliant

1. Product Overview

The Optical Transceiver Module model CC-QSS110M-SD is a high-performance 400G QSFP-DD SR8 transceiver designed for next-generation data centers and high-speed networking applications. It supports 8 independent optical channels, each operating at 26.56 GBaud, and delivers reliable transmission up to 100 meters over OM4 multimode fiber. This optical module is fully compliant with QSFP-DD MSA and CMIS 4.0 standards, ensuring broad compatibility and ease of integration.

2. Key Features

• 8-channel parallel optical interface with CDR technology
• Hot-pluggable QSFP-DD form factor
• Up to 100 m reach on OM4 MMF
• 850 nm VCSEL and PD array technology
• Low power consumption (< 10 W)
• CMIS 4.0 management interface
• MPO-16 APC connector
• Digital diagnostics monitoring (DDM)

3. Technology & Standards

This optical transceiver module utilizes PAM4 modulation and complies with industry standards including QSFP-DD MSA, CMIS 4.0, and IEC laser safety Class 1. It supports IEEE 802.3cm and 802.3cd specifications, making it ideal for high-bandensity data center deployments.

4. Working Principle

The module converts electrical signals into optical signals using a VCSEL array operating at 850 nm. Each of the 8 lanes transmits and receives data independently, enabling aggregate throughput of 400 Gbps. Integrated CDR circuits ensure signal integrity, while the built-in controller supports real-time monitoring of temperature, voltage, and optical power.
