Μονάδα πομποδέκτη SFP BlueOptics SFP-GD-BX43-BO 1250 Mbit/s

The BlueOptics SFP-GD-BX43-BO is a Single-Mode fiber SFP transceiver module designed for 1000BASE-BX-D applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 3 g, the module operates from a 3.3 V input and provides a duplex optical link using an LC simplex connector. The transceiver implements separate transmit and receive wavelengths (transmit 1310 nm, receive 1490 nm) and supports single-fiber bidirectional transmission over distances up to around 20 km when used with appropriate single-mode fiber.

Advantages

The module follows MSA standards and is compatible with MRV platforms that support the original SFP-GD-BX43 form factor and protocol, enabling straightforward replacement or expansion of existing equipment. Built with high-quality optical lasers and IC components, it offers stable optical performance, long operational life and low weight. Integrated Digital Diagnostics Monitoring (DDM/DOM) support provides real-time telemetry for supply voltage, laser bias current, transmit power, received power and temperature to aid maintenance and troubleshooting. The metal housing contributes to mechanical durability and electromagnetic resilience.

Suitable for

• 1000BASE-BX-D Ethernet links over single-mode fiber
• Fiber connections between MRV-compatible switches and routers
• Long-distance uplinks and inter-site connectivity up to ~20 km
• Storage area networks and Fibre Channel over Ethernet applications up to 1.25 Gbit/s

Key specifications

• Interface type: SFP (LC simplex connector)
• Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
• Optical wavelengths: TX 1310 nm / RX 1490 nm for bidirectional single-fiber operation
• Transmission medium: Single-mode fiber (single-fiber bidirectional)
• Typical reach: up to approximately 20 km (depends on fiber and link budget)
• Power supply: 3.3 V input
• Device material and colour: metal housing, silver
• Weight: approx. 3 g
• Digital diagnostics: DDM/DOM per SFF-8472 (supply voltage, bias current, Tx power, Rx power, temperature)

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or other MRV-compatible hardware while the device is powered down or following the host vendor’s hot-swap procedure. Connect an LC simplex single-mode patch cable between this transceiver and the remote transceiver; ensure the remote end is configured for the complementary wavelengths. Verify link status and use the host device console or management interface to check DDM values where supported. Confirm that the host device firmware accepts third-party BlueOptics modules if any vendor lock checks are present.

Recommendations

Use high-quality single-mode fiber and LC simplex patch cords to achieve the stated reach and signal quality. Ensure the network equipment supports 1000BASE-BX-D and DDM/DOM if you require diagnostic telemetry. When replacing existing modules, power down or follow the manufacturer’s hot-swap guidance and verify compatibility in a test environment before wide deployment.
