About This Part
The Finisar FTL4C1QE2L is a high-performance optical transceiver designed for 40 Gigabit Ethernet (40GbE) applications. As a member of the QSFP (Quad Small Form-factor Pluggable) family, this module adheres to the 40GBase-LR4 standard, enabling robust data transmission over single-mode fiber (SMF) for distances up to 10 kilometers. It operates by utilizing four independent 10Gbps optical lanes, which are multiplexed and demultiplexed onto a single fiber pair using LAN WDM (Coarse Wavelength Division Multiplexing) technology, typically within the 1310nm wavelength window. The FTL4C1QE2L features a duplex LC connector interface, providing a reliable, low-power, and high-bandwidth solution critical for modern network infrastructure. This Finisar transceiver is a critical component in modern data center interconnects (DCIs), enterprise networks, and campus backbones, where high-speed, long-reach optical links are essential. It is typically installed in switches, routers, and network interface cards (NICs) that require 40GbE optical connectivity. The FTL4C1QE2L supports high-density, high-bandwidth applications for telecom operators, cloud service providers, and large-scale enterprises, solving the challenge of extending 40GbE connectivity beyond the limited reach of SR4 transceivers or copper cabling. It enables efficient network upgrades from 10GbE infrastructure or consolidates multiple lower-speed links into a single, higher-capacity optical connection.
