SFP transceiver BlueOptics SFPGZX70-BO 1250 Mbit/s 1550 nm

The BlueOptics SFPGZX70-BO SFP transceiver is a single‑mode fiber optic module designed for 1.25 Gbit/s (1250 Mbit/s) data links at a 1550 nm wavelength. Housed in a metal SFP form factor with an LC duplex interface, it operates from a 3.3 V supply and weighs approximately 2 g. The module supports standard 1000BASE‑ZX optical transport over long distances when used in compatible hardware that accepts MSA‑compliant SFP transceivers.

Advantages

The metal housing provides mechanical stability and EMI shielding while keeping the module compact and lightweight. Compliance with SFP/MSA mechanical and electrical standards ensures interoperability with a wide range of switches, routers and storage devices that support 1000BASE‑ZX optics. The 1550 nm wavelength and single‑mode design enable long‑reach links with low attenuation when paired with suitable single‑mode fiber and LC duplex connectors.

Suitable for

• Long‑reach Ethernet links (1000BASE‑ZX) over single‑mode fiber
• Interconnects between switches, routers and storage systems in campus or metropolitan networks
• High‑speed optical uplinks and backbone connections
• Environments requiring MSA‑compliant, replaceable SFP optics

• Supply voltage: 3.3 V
• Weight: approx. 2 g

How to use

Insert the BlueOptics SFPGZX70-BO into a compatible SFP slot of your network device while the device is powered according to the vendor’s instructions. Connect LC duplex single‑mode patch cables to the transceiver terminals, ensuring correct transmit/receive orientation. Verify that the host device recognizes the transceiver and that the link is negotiated at the desired speed. If the host supports digital diagnostics (DDM/DOM), monitor supply voltage, temperature, transmit/receive power and laser bias current through the management interface to confirm proper operation.

Recommendations

For reliable long‑reach performance, use high‑quality single‑mode fiber and LC duplex connectors. Ensure the host hardware supports 1000BASE‑ZX optics and, if required, DDM/DOM monitoring. Avoid excessive mechanical stress on the module or patch cords and follow the device vendor’s hot‑swap and grounding guidelines.
