Tecowin módulo transceptor Cisco 40GBASE-SR4 QSFP con conector MPO, 100 m, compatible

The Tecowin QSFP-40G-SR4-C stands out for its four-lane VCSEL array design, delivering 40 Gbps over parallel multimode fiber with a single MPO/MTP-12 connector. Unlike breakout solutions, this module keeps cabling simple and latency low in high-density 40 Gigabit Ethernet aggregation links and spine-leaf fabrics.

Highlights

• 40 Gbps total bandwidth across four independent transmit and receive channels
• MPO/MTP-12 connector for parallel multi-mode fiber
• 100 m reach on OM3, 150 m on OM4
• VCSEL transmitter and PIN receiver array
• Digital diagnostics monitoring (DDM/DOM) for real-time health checks
• Hot-swappable and MSA compliant for Cisco and other QSFP systems

In daily use

This transceiver is aimed at 40 Gigabit Ethernet aggregation links, spine-leaf fabrics, and high-throughput storage. The four-lane design keeps latency low and cabling simple compared to four separate SFP+ pairs. Because it is MSA compliant, it works in Cisco switches and any other QSFP port that accepts industry-standard 40GBASE-SR4 optics. The MPO connector is keyed for polarity B, which is the common choice for structured cabling. Power draw stays under 1.5 W, so it adds little heat to dense line cards.
