SFP transceiver module BlueOptics SFP-7D-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-7D-BO is a compact fiber optic SFP transceiver module designed for single-mode optical links at a data rate of 1250 Mbit/s using a 1550 nm wavelength. Housed in a metal casing and operating from a 3.3 V supply, this silver-coloured SFP module weighs approximately 3 g and provides LC duplex connectivity for simultaneous transmit and receive over separate fibres. The module follows MSA form-factor standards and is suitable as a compatible replacement for equipment that supports equivalent 1000BASE-ZX SFP transceivers.

Advantages

The module offers stable optical transmission over long distances with a 1550 nm transmitter and receiver pair, and supports common network protocols such as Ethernet and Fibre Channel at up to 1.25 Gbit/s. Its metal housing improves mechanical durability and thermal dispersion while the small, standardized SFP form factor enables easy hot-plug installation in switches, routers and other network devices. Built according to established MSA specifications, the transceiver supports digital diagnostics (DDM/DOM) when the host hardware provides the interface.

Suitable for

• Single-mode optical links requiring up to 1250 Mbit/s throughput
• Long-reach connections, typical 1000BASE-ZX applications
• Switches, routers, storage systems and media converters with SFP ports
• Environments where EMI immunity and fiber isolation are required

Key specifications

• Interface type: SFP (MSA compliant)
• Wavelength: 1550 nm
• Maximum data transfer rate: 1250 Mbit/s
• Connector: LC duplex
• Operating voltage: 3.3 V
• Housing: metal
• Colour: silver
• Weight: approx. 3 g
• Supports Digital Diagnostics Monitoring (DDM/DOM) where host supports it

How to use

Install the SFP transceiver into a compatible SFP port on the target device while the device is powered according to the vendor's guidance for hot-plug modules. Connect LC duplex single-mode fiber patch cords ensuring correct transmit-to-receive alignment. Configure the host device network interface for the intended protocol (for example Ethernet or Fibre Channel) and verify link status. If the host system supports DDM/DOM, read diagnostic parameters such as supply voltage, laser bias current, optical output/input power and temperature to monitor link health.

Recommendations

Use single-mode LC duplex patch cords and, where applicable, patch panels or transceiver pairs from the same performance grade to achieve specified reach and signal quality. Verify compatibility with your specific switch or router firmware and enable DDM/DOM support in the host for remote monitoring. Handle the transceiver by its housing, keep connector endfaces clean and use protective caps when not in use to prevent contamination and signal loss.
