SFP transceiver module BlueOptics SFPGLX20B13-BO 1250 Mbit/s Fiber optic

The BlueOptics SFPGLX20B13-BO is a small form-factor pluggable (SFP) fiber optic transceiver module designed for single‑mode links with a maximum data rate of 1250 Mbit/s. Housed in a silver metal casing and weighing approximately 20 g, the module provides a standard SFP electrical interface and an LC simplex optical connector. It implements 1000BASE-BX-U style single-fiber operation with separate transmit and receive wavelengths to enable bidirectional transmission over one single‑mode fiber.

Advantages

The module follows MSA SFP form‑factor specifications and is compatible with equipment that supports 1000BASE-BX-U SFP transceivers, enabling straightforward hot‑plug installation in switches, routers and other networking devices. Its single‑mode LC simplex connector and distinct transmit/receive wavelengths allow long‑reach optical links while minimizing electromagnetic interference. The compact silver housing and standardized interface simplify inventory and replacement planning.

Suitable for

• 1 Gbit Ethernet and similar 1250 Mbit/s optical network links
• Long‑reach single‑mode fiber connections using LC simplex
• Switches, routers, storage systems and other network equipment with SFP ports
• Environments requiring hot‑pluggable, MSA‑compliant transceivers

Key specifications

• Form factor: SFP (Small Form‑Factor Pluggable)
• Maximum data transfer rate: 1250 Mbit/s
• Optical modality: Single‑mode fiber, single‑fiber bidirectional (BX)
• Connector type: LC simplex
• Typical transmit/receive wavelengths: separate TX and RX wavelengths for BX operation (single‑fiber)
• Housing colour: Silver metal casing
• Weight: approx. 0.02 kg
• Compliance: MSA SFP mechanical and electrical specifications

How to use

Insert the BlueOptics SFPGLX20B13-BO module into a compatible SFP slot on network equipment until it seats firmly; the module supports hot‑plug operation if the host device allows it. Connect an LC simplex single‑mode fiber patch cord to the module, observing the correct orientation for the single‑fiber bidirectional link (ensure TX on one end aligns with RX on the opposite end). Verify link status and negotiate speed and duplex according to the host device's interface settings. If available, enable or verify Digital Diagnostics/DOM support on the host to monitor operating parameters.

Recommendations

Use high-quality single‑mode LC simplex patch cords and, when possible, test interoperability with the specific switch or router model before large deployments. Ensure the host device supports 1000BASE‑BX‑U and any required digital diagnostics functions to access transceiver monitoring data.
