Description

The QSFP-40G-LR4-S is a 40 Gigabit Ethernet Quad Small Form-Factor Pluggable (QSFP) transceiver module designed for long-reach optical connections. It utilizes four wavelengths (LR4) to transmit data over single-mode fiber (SMF) up to 10 kilometers. This module is commonly used in data centers and telecommunications networks to provide high-bandwidth connectivity between switches, routers, and other network devices. The “S” at the end often denotes a specific vendor or compatibility, but generally, this module provides 40 Gigabit Ethernet connectivity over long distances via fiber.
