SFP-transceivermodule BlueOptics SFP-GLSD-70-A-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-GLSD-70-A-BO is a single‑mode fiber SFP transceiver module designed for 1000BASE-ZX and similar gigabit optical links. It supports a maximum data rate of 1250 Mbit/s and operates at a nominal wavelength of 1550 nm. The module comes in a metal housing, weighs approximately 3 g, and uses a standard SFP interface with an LC duplex optical connector. It requires a 3.3 V supply and is intended for use in networking equipment that accepts MSA‑compliant SFP transceivers.

Advantages

The module follows MSA SFP form‑factor standards, which helps ensure interoperability with a wide range of switches, routers and storage devices that support compatible 1000BASE‑ZX transceivers. Its metal housing provides mechanical stability and thermal dissipation while the lightweight design keeps module weight minimal. Operating at 1550 nm and rated for up to 1250 Mbit/s, it is suitable for long‑reach single‑mode fiber links when used with appropriate patch cords and fiber infrastructure.

How to use

Install the transceiver into an SFP slot of a compatible network device while the device is powered according to the vendor guidance or hot‑plug as supported. Connect LC duplex single‑mode patch cords to the transmitter and receiver ports, ensuring correct TX/RX orientation and proper fiber polishing/cleaning. Configure the host device network settings to enable the link and verify operational parameters such as link speed and diagnostics through the device management interface. Confirm that the receiving endpoint and any intermediate equipment support 1550 nm single‑mode optics and the expected link distance.

Recommendations

Use high‑quality single‑mode LC duplex patch cords and clean connector endfaces before mating. Verify compatibility with the host hardware and enable Digital Diagnostic Monitoring (DDM/DOM) on platforms that support it to monitor supply voltage, optical power and temperature for proactive maintenance.
