Description
The Cisco QSFP-40G-LR4-S is a high-performance, hot-swappable transceiver module designed for 40 Gigabit Ethernet applications over single-mode fiber. Built in a compact QSFP+ form factor, it supports a maximum link length of up to 10 kilometers using LC duplex connectors. Utilizing four separate 10Gbps channels multiplexed into a single fiber pair, this module ensures efficient data transmission with low power consumption. Its compliance with IEEE 802.3ba and QSFP+ MSA standards guarantees seamless integration with a wide range of Cisco networking equipment.
Equipped with digital optical monitoring (DOM) capabilities, this transceiver provides real-time diagnostics for key parameters such as temperature, optical power, and voltage levels. It operates on a wavelength range of 1270nm to 1330nm, ensuring stable and reliable long-range connectivity. Designed for data centers, enterprise networks, and service provider environments, it delivers high-speed performance while maintaining cost efficiency. A durable metal housing enhances heat dissipation and electromagnetic interference (EMI) resistance, ensuring long-term reliability in demanding network conditions.
