Accortec X140 40G QSFP+ LC BiDi MM Transceiver (100m)

The Accortec X140 40G QSFP+ LC BiDi MM Transceiver is engineered for high-demand data centers and enterprise networks where speed, reliability, and scalability matter. This 40G QSFP+ BiDi transceiver brings together advanced bidirectional optics and a compact interface to deliver robust, low-latency connectivity over multimode fiber for deployments up to 100 meters. Ideal for uplinks, stacked switches, and dense rack installations, the X140 is designed to streamline your path to 40G connectivity without sacrificing compatibility or performance.

• High-performance 40G connectivity: The X140 supports data rates up to 40 Gbps, enabling rapid, parallel data transfer across server and switch fabrics. This makes it a strong choice for data-intensive workloads, virtualization, and high-traffic applications where latency must stay in check and bandwidth must scale with demand. With a QSFP+ form factor, you gain a single-port module capable of delivering multi-gigabit performance per channel while preserving valuable rack space in dense deployments.
• BiDi optics for efficient fiber utilization: The BiDi (bidirectional) design uses dual wavelengths on a single multimode fiber strand, allowing two channels to transmit and receive simultaneously in opposite directions. This approach reduces the number of fiber strands required in crowded data center corridors and simplifies cabling, especially when upgrading existing multi-fiber layouts. The result is easier installs, fewer cross-connections, and cleaner patch panels while delivering comparable throughput to traditional parallel optics.
• Designed for 100m multimode fiber links: The X140 is optimized for multimode fiber runs commonly found in data centers and campus networks, supporting reliable operation up to 100 meters. This distance fits most top-of-rack to aggregation-layer uplinks and short-haul interconnect paths, enabling cost-efficient deployments without compromising performance. Its multimode compatibility helps leverage existing fiber infrastructure and reduces the need for costly rewiring projects.
• LC duplex connectors and plug-and-play deployment: The module features LC duplex connectors, aligning with standard multimode fiber cabling. This design supports straightforward insertion into compatible switches and routers with minimal downtime. The X140’s rugged QSFP+ enclosure is built for hot-swapping in many enterprise devices, allowing technicians to upgrade or replace transceivers with minimal service interruption.
• Reliability, scalability, and broad compatibility: Built to withstand the rigors of busy network environments, the X140 is suitable for data centers, server farm interconnects, and enterprise backbones. Its capability to scale with growing bandwidth demands makes it a practical investment for organizations pursuing phased 40G deployments. The module is designed to integrate with a wide range of 40G-capable switches and routers that support QSFP+ interface, enabling straightforward upgrades and consistent network performance.

How to Install Accortec X140 40G QSFP+ LC BiDi MM Transceiver

• Power down and prepare: Before installation, power down the target device if required by your maintenance policy. Disconnect any auxiliary cables and ensure you have a clean, static-free workspace to prevent ESD damage to the module or other components.
• Inspect the port and module: Check the QSFP+ port on the switch or router for debris. Handle the X140 by the edges to avoid touching the optical connectors or circuitry. Confirm the module is the correct orientation for insertion.
• Insert into the QSFP+ port: Align the X140 with the QSFP+ cage and gently slide it into the port until it seats securely. A proper seat should feel firm, and the module should be flush with the faceplate. Do not force the module if resistance is encountered.
• Connect the fiber cabling: Attach the LC duplex fiber cables to the module’s LC connectors, ensuring correct transmit/receive orientation according to your network design. Use appropriate fiber types and bend-radius compliant cables to maintain signal integrity.
• Power and verify: Restore power to the device and monitor the port status. Use the device’s management interface to verify link establishment, LED indicators, and any transceiver-specific diagnostics. If a link does not come up, double-check fiber polarity, cable quality, and switch configuration.
• Test and document: Perform a basic throughput test or loopback test to confirm 40G performance, then document the installation for future maintenance and compliance records. Replace cabling or reseat the module if any stability issues are observed during testing.

Frequently Asked Questions

• What is the Accortec X140 40G QSFP+ LC BiDi MM Transceiver?
  It is a 40 Gigabit per second bidirectional transceiver designed for multimode fiber, leveraging a QSFP+ form factor and LC duplex connectors to deliver high-speed 40G connectivity over distances up to 100 meters in data center and enterprise networks.
