SFP-transceiver BlueOptics SFPGZX70D-W-BO 1250 Mbit/s 1550 nm

The BlueOptics SFPGZX70D-W-BO is a compact SFP transceiver module designed for fiber-optic 1000BASE-ZX links. It supports a maximum data transfer rate of 1250 Mbit/s at a wavelength of 1550 nm, housed in a metal casing and powered by a 3.3 V supply. With a lightweight construction of approximately 3 g and an LC duplex optical interface, this module transmits and receives signals simultaneously over separate fibres to provide reliable long-range connectivity and immunity to electromagnetic interference.

Advantages

This SFP transceiver offers a lightweight metal housing for robust mechanical protection and thermal stability. It supports 1250 Mbit/s throughput suitable for gigabit network segments and operates at 1550 nm to enable extended reach in single-mode fibre applications. The module is compatible with digital diagnostic monitoring (DDM/DOM) when supported by the host device, allowing remote readout of supply voltage, laser bias current, transmitter output power, receiver input power and temperature. Designed with components from established vendors, the module targets long operational lifetime and high availability.

Suitable for

• Long-distance single-mode fibre links (1000BASE-ZX)
• Data center uplinks and backbone connections
• Telecommunications and metro ring applications
• Replacement or upgrade of SFP ports in switches and routers

How to use

Ensure the host device supports SFP 1000BASE-ZX transceivers and DDM/DOM if diagnostic monitoring is required. Insert the transceiver into an empty SFP slot until it clicks into place, and connect LC duplex single-mode fibre patch cords to the TX and RX ports, observing correct polarity. Power the host device and verify link status through the switch or router interface. For optimal signal quality, use appropriate single-mode patch cables and, if needed, route through a compatible patch panel.

Recommendations

To achieve the best link performance and range, use single-mode fibre cables designed for 1550 nm operation and ensure correct fibre polarity. Confirm DDM/DOM support in the networking equipment to monitor optical parameters remotely. Store and handle the transceiver in ESD-safe conditions and avoid contamination of connector endfaces by keeping dust caps on when not connected.
