SFP-transceivermodule BlueOptics SFP-GSX-LCI-AE-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-GSX-LCI-AE-BO is a single‑port SFP fiber‑optic transceiver module designed for 1000Base‑SX links with a maximum data rate of 1250 Mbit/s. It operates at an 850 nm wavelength over multimode fiber and uses an LC duplex optical connector. The module is housed in metal for mechanical stability, runs from a 3.3 V supply and weighs approximately 3 g, making it compact and simple to install in SFP‑compatible network equipment that follows MSA standards.

Advantages

The module supports standard 1000Base‑SX optical signal transmission and is compatible with a wide range of network switches, routers and storage systems that accept MSA‑compliant SFP transceivers. Metal housing provides durability and EMI shielding while the small form factor allows dense port populations. Support for multimode fiber and LC duplex connectors enables simultaneous transmit and receive channels. The transceiver is suitable for short‑range Gigabit Ethernet and related protocols up to 1.25 Gbit/s.

Suitable for

• Gigabit Ethernet connections over multimode fiber (1000Base‑SX)
• Interconnects between switches, routers and patch panels in data centers and server rooms
• Storage area network links and network appliances supporting SFP modules
• Upgrading or replacing MSA‑compliant SFP transceivers in existing hardware

Key specifications

• Interface type: SFP (small form‑factor pluggable)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength: 850 nm (multimode fiber)
• Connector type: LC duplex
• Typical reach on multimode fiber: suitable for standard 1000Base‑SX distances (up to several hundred meters depending on fiber type)
• Power supply: 3.3 V input
• Housing: metal (silver color)
• Weight: approx. 0.003 kg

How to use

Insert the SFP transceiver into an SFP port of a compatible switch, router or other network device while the host device is powered down or following the vendor’s hot‑swap procedure. Connect LC duplex multimode fiber patch cords to the module, observing correct Tx/Rx orientation. Verify that the host device recognizes the module and that the link negotiates to Gigabit speed. If available, enable Digital Diagnostics Monitoring (DDM/DOM) in the host to read real‑time parameters such as supply voltage, temperature and optical power for troubleshooting and maintenance.

Recommendations

Use high‑quality multimode fiber and LC duplex patch cords matched to the expected link distance and fiber grade. Confirm SFP compatibility with the target hardware and firmware; enable DDM/DOM support when remote monitoring is required. Avoid excessive bending of fiber cables and follow ESD precautions when handling the transceiver to ensure reliable operation and long service life.
