SFP-lähetin-vastaanotinmoduuli BlueOptics SFP-1G-SX-LE-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-LE-BO is an SFP fiber-optic transceiver module designed for 1 Gigabit-class optical links. It supports a maximum data transfer rate of 1250 Mbit/s and operates at an 850 nm wavelength over multimode fiber. Housed in a compact metal casing and powered by a 3.3 V supply, the module weighs approximately 3 g and uses an LC duplex connector for transmit and receive paths. The transceiver follows MSA-compatible SFP form-factor standards and is intended for integration into network switches, routers and storage interfaces that accept standard 1000Base-SX SFP modules.

Advantages

The module delivers gigabit-capable optical connectivity with an 850 nm VCSEL-based transmitter and receiver optimized for multimode fiber, enabling reliable short-reach links. Its metal housing provides mechanical durability and thermal dissipation, while the low weight and standard SFP form factor simplify installation and hot-swap replacement. The BlueOptics unit adheres to SFP/MSA interfaces and supports digital diagnostic monitoring when the host hardware exposes DDM/DOM, allowing remote readout of operating parameters.

Suitable for

• Short-range multimode fiber links (1000Base-SX) up to typical multimode distances
• Gigabit Ethernet connections in switches and routers
• Server and storage uplinks that accept SFP 1G transceivers
• Network upgrades and replacements where SFP form-factor compatibility is required

How to use

Install the BlueOptics SFP-1G-SX-LE-BO by inserting the SFP cassette into a compatible SFP port on the switch, router or storage device until it latches. Connect LC duplex multimode fiber patch cords to the module’s transmit and receive ports, ensuring correct polarity. Power and link negotiation are handled by the host device; verify link status through the host interface. If supported by the host, enable or query DDM/DOM to monitor supply voltage, laser bias current, transmit output power, receive input power and device temperature for diagnostic purposes.

Recommendations

Use good-quality multimode fiber and matched LC duplex patch cords to achieve optimal link performance. Confirm that the host device firmware and hardware support 1000Base-SX SFP modules and, if required, the DDM/DOM feature. Avoid bending or stressing fiber cables near the module and observe ESD precautions during handling and installation.
