Overview
PYP:40GBASE-CSR QSFP Transceiver Module with
Cisco QSFP-40G-CSR-S (S-Class)
The QSFP-40G-CSR-S is a pluggable optical transceiver with a duplex LC connector interface used for connectivity using MultiMode Fiber (MMF). The Cisco 40GBASE-CSR Modules support link lengths of 300 meters and 400 meters, respectively, on laser-optimized OM3 and OM4 multimode fibers. Customers benefit through the reuse of their existing 10 gigabit duplex MMF infrastructure as they migrate to 40 Gigabit Ethernet, while maintaining the same supported link distances as 10G Ethernet. Each QSFP-40G-CSR-S operates at four different wavelengths. Each of the four wavelengths operates at 10G over existing duplex multimode fiber using standard LC connectors. The Cisco QSFP-40G-CSR-S transceiver supports FCoE.
- 40Gigabit Ethernet - Designed to provide high-performance Ethernet connection while minimizing power and CPU cycles' utilization
- With its thicker diameter to carry the light of multiple wavelengths, multi-mode fibre optic cable supports the high bandwidth to carry more information with greater fidelity
- Supports optical fibre cable for durable performance, minimal signal loss, and fast data transfers to greater distances
- With 40GBase-SR technology, enjoy up to 40Gbps data transfer rate over optical fibre cable
