Moxa Compatible SFP-1G20ALC - Functionally Identical 1000BASE-BX Bi-Di SFP 1310nm TX/1550nm RX 20km w/DOM Single-mode Simplex LC

Engineered for reliability in enterprise, industrial, and data-center networks, this Enet Moxa-compatible SFP-1G20ALC delivers functionally identical performance to the original Moxa module. It enables seamless 1000BASE-BX Bi-Di operation, supports robust diagnostics through Digital Optical Monitoring (DOM), and is designed to thrive in challenging environments with a lifetime warranty. Whether you’re refreshing aging infrastructure, integrating remote sites, or deploying long-haul fiber links, this SFP module offers a trusted, plug-and-play upgrade path that ensures compatibility, repeatable results, and simplified inventory management.

• BiDi 1000BASE-BX performance — This module supports 1000BASE-BX Bi-Di operation with a 1310nm transmitter and a 1550nm receiver, enabling duplex communication over a single fiber pair. By leveraging bi-directional optics, it reduces fiber requirements, simplifies cable management, and helps you maximize switch port density without compromising throughput. It’s an ideal choice for networks where fiber availability is limited or where you need to extend reach without laying new fiber infrastructure.
• Long-reach single-mode fiber link — Designed for up to 20 kilometers of distance on standard single-mode fiber, this SFP provides reliable, high-quality transmission for campus backbones, remote sites, or industrial facilities. The 1310nm/1550nm wavelength combination minimizes dispersion over long paths, preserves signal integrity, and supports stable 1 Gbps performance across the link, even in environments with challenging fiber paths.
• Digital Optical Monitoring (DOM) for proactive management — DOM compatibility means your network management system can read real-time optical parameters such as transmitted and received optical power, temperature, laser bias current, and supply voltage. This visibility enables proactive maintenance, quick fault isolation, and improved uptime for critical links, reducing mean time to repair (MTTR) and enabling data-driven capacity planning.
• Moxa-compatible, tested, and USA-supported — Built to be plug-compatible with Moxa devices and other BX BiDi-capable switches and routers, this module is programmed, tested, and supported in the United States. It provides seamless interoperability with a wide range of vendors, ensuring a smooth rollout across mixed-brand networks. The package includes a lifetime warranty, offering lasting assurance for enterprise deployments and industrial applications alike.
• Easy integration, reliability, and cost-efficiency — With plug-and-play, hot-swappable design suitable for SFP slots, this module minimizes downtime during upgrades. It uses a compact form factor with a single-mode LC simplex connector, ensuring compatibility with common fiber cabling. The module is engineered for robust operation in demanding environments, featuring well-managed power consumption, dependable MTBF figures, and a cost-effective path to extending the life of your existing network hardware.
