SFP transceiver module BlueOptics H-BX20-SFP/A-D-BO 1250 Mbit/s

The BlueOptics H-BX20-SFP/A-D-BO is a single‑mode SFP transceiver module designed for fiber optic links with a maximum data rate of 1250 Mbit/s. Housed in a compact metal casing and weighing approximately 20 g, the module follows MSA form‑factor conventions and meets CE, RoHS and FCC standards. It implements a 1000BASE‑BX‑D optical interface with an LC simplex connector and supports one‑way transmit and receive wavelengths suitable for long‑distance single‑mode fiber links.

Advantages

This SFP transceiver offers a compact metal design for reliable mechanical protection and thermal performance. It supports 1250 Mbit/s operation and is compatible with hardware platforms that accept standard MSA SFP modules. The module is factory tested for optical performance and basic interoperability and includes support for digital diagnostics (DDM/DOM) when the host device supports it. Compliance with CE, RoHS and FCC ensures adherence to common regulatory and environmental requirements.

Suitable for

• Point‑to‑point single‑mode fiber connections up to typical vendor‑specified distances for 1000BASE‑BX‑D
• Switches, routers and network appliances with SFP ports that support MSA SFP transceivers
• Optical uplinks in enterprise and carrier Ethernet or Fibre Channel over Ethernet applications

Key specifications

• Interface type: SFP (MSA compliant)
• Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
• Optical type: single‑mode fiber, LC simplex connector
• Transmit/receive wavelengths: typical 1310 nm (TX) and 1490 nm (RX) for BX‑D operation
• Housing: metal casing
• Weight: approx. 0.02 kg
• Standards: 1000BASE‑BX‑D optical specification

How to use

Insert the BlueOptics SFP module into a compatible SFP port on the host device until it latches securely. Connect an LC simplex single‑mode fiber patch cable observing the correct TX/RX orientation for BX‑D operation. Ensure the host device supports the required optical protocol and, if DDM/DOM is to be used, that the host firmware exposes diagnostic registers. After insertion, verify link status on the host and test the optical link power and signal if required.

Usage recommendations

Install and remove the transceiver with the host device powered down if the host vendor recommends hot‑swap protection is not available; otherwise follow the hardware vendor’s hot‑swap procedures. Use appropriate single‑mode LC simplex patch cords and, for best results, connect via compatible patch panels or directly to another BX‑D transceiver. Monitor DDM/DOM parameters where supported to track supply voltage, laser bias current, output/input power and temperature for preventive maintenance.
