SFP transceiver BlueOptics GLC-BX-D-1490D-20-BO 1250 Mbit/s Silver

The BlueOptics GLC-BX-D-1490D-20-BO is an SFP fiber optic transceiver designed for single-mode links operating at up to 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, this module follows MSA form-factor standards and provides a reliable optical interface with LC simplex connectivity for point-to-point transmission. It implements bi-directional operation with separate transmit and receive wavelengths suitable for long-reach single-mode fiber links.

Advantages

This SFP transceiver offers a compact metal housing that supports stable thermal and mechanical performance in rack environments. It is compatible with 1000BASE-BX-D applications and supports data rates up to 1.25 Gbit/s while maintaining a low weight for easy handling and installation. The module is designed for high availability with a long mean time between failures (MTBF) and adherence to MSA mechanical and electrical specifications for broad interoperability with industry-standard equipment.

Suitable for

• Single-mode fiber Ethernet links up to 1.25 Gbit/s
• Point-to-point connections between switches and routers using LC simplex connectors
• Network upgrades or replacements in data center and enterprise environments
• Environments requiring MSA-compliant, hot-pluggable SFP modules

Key specifications

• Interface type: SFP (MSA-compliant)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Fiber type: single-mode (bi-directional wavelengths for BX operation)
• Connector: LC simplex
• Housing: metal
• Weight: approx. 0.02 kg
• Typical operational lifetime indicator: MTBF ~1,000,000 hours

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or other network device while the host device is powered on or according to the host’s hot-plug procedure. Connect a single-mode LC simplex patch cable between this transceiver and the corresponding remote transceiver, observing correct fiber polarity for the bi-directional (BX) link—one fiber for transmit and receive over separate wavelengths. Verify link status and speed on the host device and, if available, enable or consult the digital diagnostic monitoring (DDM/DOM) information through the host to monitor parameters such as supply voltage, laser bias current, optical output and received power, and temperature.

Recommendations

Ensure that the network hardware supports the specific BX wavelength pair and DDM/DOM features if those functions are required. Use quality single-mode LC patch cords and, where possible, test compatibility with the target device. Observe electrostatic discharge precautions when handling the module and follow manufacturer guidance for insertion and removal to maintain connector and transceiver integrity.
