ZYXEL SFPBX1490D: 1490nm TX / 1310nm RX Single-Mode Gigabit SFP Transceiver Module

Experience robust, long-range fiber connectivity with the ZYXEL SFPBX1490D. This high-performance Gigabit SFP transceiver is purpose-built for single-mode fiber networks, delivering precise wavelength separation (1490 nm transmit and 1310 nm receive) in a compact, hot-pluggable package. With a single LC duplex interface and the 1000Base-BX standard, it is purposefully designed for enterprise data centers, campus networks, and backbone links that demand reliable 1 Gbps data rates over substantial distances. Whether you’re upgrading uplinks, extending a metropolitan network, or integrating new optical paths, the SFPBX1490D provides a seamless, scalable solution that minimizes downtime and optimizes fiber utilization.

• Long-haul single-mode performance: The SFPBX1490D is engineered for single-mode fiber and supports 1000Base-BX links over distances up to 20 kilometers. The 1490 nm transmitter and 1310 nm receiver are chosen to maximize link budget and minimize dispersion in standard single-mode plant, enabling stable, high-quality data transmission across campus and metro networks. This makes it ideal for inter-building links, data-center cores, and WAN backbones where reliable 1 Gbps throughput is essential.
• Bidirectional, single-fiber capability: Leveraging the 1000Base-BX standard, this module transmits on one wavelength while receiving on the opposite wavelength on a single optical fiber. With TX at 1490 nm and RX at 1310 nm, you can dramatically reduce fiber counts and simplify network design, while preserving full-duplex, high-speed performance across extended distances.
• Plug-and-play, with LC duplex connection: The SFPBX1490D arrives in a hot-pluggable SFP form factor, compatible with a wide range of SFP-enabled switches, routers, and media converters. It uses a single LC duplex connector for optical fiber, providing an easy, install-and-forget upgrade path that minimizes network downtime and maintenance complexity in dense deployments.
• Reliable interoperability and standards alignment: Built to the SFP industry standard, the ZYXEL transceiver ensures interoperability with multiple vendors and devices that support 1000BASE-BX. It adheres to fundamental SFP MSA specifications, delivering predictable performance, simple cross-vendor integration, and a robust lifecycle that aligns with enterprise procurement and support processes.
• Designed for enterprise-grade data networking: Whether you are expanding core-to-edge uplinks, connecting data centers, or linking regional sites, the SFPBX1490D offers dependable 1 Gbps performance with stable optics, efficient power consumption, and a form factor that fits neatly into dense chassis environments. Its compact footprint, hot-swapping capability, and proven reliability support aggressive deployment timelines and long-term network growth.

How to install ZYXEL SFPBX1490D

• Power down or suspend the switch, router, or media device before installation to prevent latch-up or electrical damage.
• Locate an available SFP port on the device and remove the protective cover from the SFP slot; verify there is no physical obstruction or debris.
• Insert the SFPBX1490D firmly into the SFP slot until you hear a click, ensuring the module is fully seated and aligned with the connector pins.
• Attach the optical fiber using a compatible LC duplex patch cord; ensure the TX side (1490 nm) connects to the RX side of the corresponding device and the RX side (1310 nm) to the TX side, if applicable to the network design.
• Secure the fiber connectors with the appropriate strain relief and verify the link status on both ends; power up the device and monitor the interface for a stable link and negotiated speed.
• Configure the device’s uplink port as 1000BASE-BX and ensure any necessary VLAN, spanning-tree, or routing policies align with the new link.
• Test throughput and latency across the link to confirm performance meets expectations; monitor for dispersion, attenuation, or any signaling anomalies.
• Document the upgrade in your change management records, including the installation date, port mappings, and any device-specific configuration notes.
