Meraki Compatible MA-QSFP-40G-LR4: 40GBASE-LR4 QSFP+ Transceiver for 10km SMF

This description presents a high‑performance, plug‑and‑play solution designed for Meraki environments that demand the reliability of a functionally identical transceiver. The Meraki Compatible MA-QSFP-40G-LR4 is engineered to deliver the same 40GBASE-LR4 capabilities as the OEM, while offering a cost‑effective alternative that does not compromise on performance, monitoring, or compatibility. Built for data centers, campus backbones, and enterprise networks, this QSFP+ transceiver supports long‑haul single‑mode fiber links, enabling high‑speed connectivity across buildings, campuses, and metropolitan networks. Whether you are refreshing an existing Meraki deployment or expanding capacity, this module provides a stable, compliant, and future‑proof option that aligns with modern Ethernet standards and network design principles.

• Seamless Meraki compatibility: Functionally identical to the OEM MA-QSFP-40G-LR4, designed to work with Meraki switches and routers where 40GBASE-LR4 connectivity is required. The module is built to slot into standard QSFP+ ports without bespoke configuration, delivering reliable performance in production environments.
• Four‑channel LR4 wavelengths: Each transceiver supports the four optical wavelength lanes used by 40GBASE-LR4 — 1270 nm, 1290 nm, 1310 nm, and 1330 nm. This multi‑channel approach enables effective long‑haul data transmission over single‑mode fiber, optimizing bandwidth while maintaining signal integrity across the link.
• Long‑reach performance for SMF: Transceiver reach extends up to 10 kilometers on standard single‑mode fiber (SMF). This makes it ideal for data center interconnects, campus backbones, and multi‑site networks where devices are separated by significant distances but require high‑speed, low‑latency connectivity.
• Duplex LC fiber interface: The module uses a standard duplex LC connector, ensuring compatibility with widely deployed SMF cabling. The transceiver integrates cleanly into existing fiber plant, supporting straightforward fiber pairing and alignment with minimal installation complexity.
• Digital Optical Monitoring (DOM) and quick diagnostics: Built‑in DOM provides real‑time telemetry for the transceiver’s optical parameters. Operators can monitor optical power, temperature, supply current, and other key metrics via management interfaces, enabling proactive fault detection and faster troubleshooting.

How to install Meraki Compatible MA-QSFP-40G-LR4

Install this module with standard QSFP+ ports on compatible Meraki devices. Follow these general steps to ensure a smooth installation and optimal performance:

• Power down or follow your device’s recommended hot‑swap procedure as applicable. In many deployments, these transceivers are designed for hot‑swap, but always consult your equipment guidelines before handling.
• Inspect and prepare the fiber links. Use clean, terminated SMF cables with duplex LC connectors. Ensure the transmit (Tx) and receive (Rx) fibers are properly matched to the corresponding ports on the network equipment.
• Insert the MA‑QSFP‑40G‑LR4 module into the QSFP+ slot until it seats with a definitive click. Ensure the module is fully seated and the port LED indicators reflect a healthy state per your device’s management interface.
• Connect the fiber pairs to the appropriate transceiver channels. Adhere to your network design for Tx/Rx orientation, and confirm polarity is correct to avoid link issues.
• Power on the device (if required) and navigate to your Meraki dashboard or network management system. Verify link status, speed, and endpoint identity. If DOM is enabled and supported by your equipment, review the optical metrics to confirm link quality.
• Run end‑to‑end tests to confirm throughput and error rates. Monitor performance over time and set up alerts for any degradation in optical power, temperature, or link health.

Important considerations for best results

To maximize reliability and performance with the MA‑QSFP‑40G‑LR4, consider standard best practices for fiber networks: maintain clean connectors, protect fiber paths from excessive bending radius, isolate sensitive components from environmental stress, and use appropriate link budgets for your topology. Although this transceiver is designed for plug‑and‑play use in Meraki environments, performance can be influenced by the optical budget, fiber quality, and the overall health of the network path. If you encounter issues, verify DOM readings, confirm compatibility with your specific Meraki model and firmware version, and review the device’s logs for any port‑level anomalies.
