QSFP DD 400G SR4 OPTICAL TRANSCEIVER MODULE

SR4 optical module in aviation

400G SR4 transceivers are optical modules designed to support 400 gigabits per second (Gbps) data rates over short distances. First, let's clarify what VR, SR, DR, FR, LR, ER, and ZR stand for, so that we can understand and identify them: VR (Very Short Range): Transmission distance usually 0~100 meters, using multimode fiber for short data center connections. This article explains the engineering differences, the physical cabling and connector implications, performance characteristics, and real-world use cases so you can pick the right part for. As the new benchmark for multimode transmission, this module leverages a 4×100G PAM4 parallel architecture and OSFP packaging advantages to deliver 400Gbps.

Companies with 400g optical module mass production capability

More than 10 companies, including Arista Networks, DELL, EdgeCore, Mellanox, and FiberMall, presented 400G optical modules at OFC 2020. 400G Optical Module by Application (Data Communication, Telecom, Other), by Types (Less Than 1 km, 1 km, 2 km, 10 km, Others), by North America (United States, Canada, Mexico), by South America (Brazil, Argentina, Rest of South America), by Europe (United Kingdom, Germany, France, Italy, Spain. To address these demands, operators are increasingly adopting 400G optical modules—compact, pluggable transceivers capable of delivering up to 400 Gbps per port. This shift is driven by multiple forces: hyperscale data centers require greater east-west bandwidth to support massive internal data. BOSTON (January 7, 2025) – Total shipments of leading-edge datacom optical modules are projected to tally over $9 billion for 2024, according to the latest Optical Components Report from research firm Cignal AI. The transition from legacy 100G and 200G modules to 400G modules is gaining momentum, as organizations seek to achieve higher throughput, reduced latency, and improved energy efficiency. The growing emphasis on digital transformation, coupled with the expansion of 5G networks and edge computing. 8 billion in 2025 and is projected to grow at a compound annual growth rate (CAGR) of 16.

How big is a 400g optical module

The 400G optical module predominantly utilizes 50G electrical lanes, often structured as 8 lanes of 50G (8x50G) to achieve 400G throughput. Common form factors include QSFP-DD (Quad Small Form-factor Pluggable Double Density) and OSFP. PAM4 allows each symbol to represent two bits of information, effectively doubling the data rate compared to traditional NRZ (Non-Return-to-Zero) modulation 1. 400G DR4 is commonly employed for high-speed communication links within a data center at short to medium distances. In practice, the DR4 type is commonly regarded as the primary option for achieving a balance between performance, economy, and energy efficiency. 400G optical modules offer a range of technical advantages that make them well-suited for modern high-speed networks: High Bandwidth Density Each module supports 400 Gbps via 4×100Gbps or 8×50Gbps lanes, enabling dense connectivity without increasing port counts.
