About This Part

The Lumentum 81.71T-Q40GLR4-R6 is a high-performance optical transceiver designed for 40 Gigabit Ethernet applications. This hot-pluggable QSFP+ (Quad Small Form-factor Pluggable Plus) module provides robust connectivity, adhering to the IEEE 802.3ba 40GBASE-LR4 standard. It operates at a nominal wavelength of 1310nm and is engineered to transmit 40Gbps data over single-mode fiber (SMF) for distances up to 10 kilometers. The LR4 designation signifies its use of four independent 10Gbps lanes, each transmitted on a distinct wavelength within the 1310nm window, which are then optically multiplexed onto a single fiber pair for transmission and de-multiplexed at the receiver end. This advanced Lumentum module ensures reliable, high-bandwidth data transfer crucial for modern network infrastructure. This Lumentum QSFP+ transceiver is extensively deployed in environments demanding high-density, high-speed interconnects, such as data centers, large enterprise networks, and campus backbones. It facilitates critical links between core switches, routers, and servers, enabling seamless 40GbE connectivity over moderate distances. Telecom operators, cloud service providers, and large-scale organizations leverage the Part Number 81.71T-Q40GLR4-R6 to address escalating bandwidth requirements for inter-rack, inter-building, and metro-area network segments. It serves as an ideal solution for upgrading existing 10GbE infrastructures to 40GbE, particularly where single-mode fiber is already in place, thereby optimizing network performance without necessitating extensive and costly fiber plant overhauls. Its deployment significantly enhances network scalability and operational efficiency. Revo Distribution Limited specializes in providing cost-effective infrastructure solutions to B2B clients by offering used and refurbished units of essential network components like the Lumentum 81.71T-Q40GLR4-R6. For telecom operators and data centre providers facing budget constraints or rapid expansion needs, acquiring these high-quality, pre-owned transceivers from Revo allows them to expand or upgrade their networks efficiently and sustainably. Each unit undergoes rigorous testing to ensure it meets performance specifications, providing a reliable alternative to new equipment at a significantly reduced capital expenditure. By extending the operational lifecycle of critical network hardware, Revo's inventory not only supports immediate infrastructure demands but also contributes to a more sustainable circular economy within the telecom and data center industries.
