SFP-transceivermodule BlueOptics SFP-20EDH-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-20EDH-BO is a compact SFP transceiver module designed for single-mode fiber links. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 1550 nm. Housed in a metal casing with a silver finish and weighing approximately 3 g, the module uses a standard SFP interface and requires a 3.3 V supply. The transceiver provides bidirectional optical transmission and fits SFP-compliant ports for use in network equipment that accepts compatible 1000BASE-ZX SFP modules.

Advantages

The module’s metal housing offers mechanical durability and reliable thermal characteristics while its small form factor enables easy installation in populated SFP ports. Operating at 1550 nm with a 1250 Mbit/s line rate, it supports long-distance single-mode connections when paired with appropriate fiber and LC Duplex connectors. The SFP interface and adherence to MSA-based form factor ensure broad compatibility with equipment that accepts compatible 1000BASE-ZX SFP transceivers.

Suitable for

• Single-mode fiber Ethernet links up to gigabit-class speeds
• Interconnection between switches, routers and storage systems supporting compatible SFP modules
• Long-reach optical links when used with appropriate single-mode fiber and LC Duplex connectors

Key specifications

• Interface type: SFP
• Maximum data transfer rate: 1250 Mbit/s

• Housing: metal, silver colour
• Supply voltage: 3.3 V
• Weight: 0.003 kg

How to use

Power down or follow hot-swap procedures recommended by your hardware vendor before inserting the transceiver into an SFP port. Insert the module until it latches, then connect LC Duplex single-mode patch cords to the transmit and receive ports. Configure the host device to recognize an SFP transceiver if necessary and verify link status through the device’s management interface. When removing the module, follow the equipment supplier’s removal instructions to avoid damage.

Recommendations

Use high-quality single-mode LC Duplex patch cords and follow the equipment vendor’s compatibility guidelines. Confirm that your network hardware supports 1000BASE-ZX compatible SFP modules and digital diagnostic monitoring (DDM) features if you require real-time transceiver diagnostics. Store unused modules in anti-static packaging and handle them by the casing to avoid contaminating the optical interfaces.
