## Long description

The BlueOptics BO05C856S5D 1000BASE-SX SFP transceiver is a compact, hot-pluggable optical module that supports gigabit Ethernet transmission over multimode fiber at a wavelength of 850 nm. Designed for short-range links, this SFP module fits standard SFP ports on switches, routers and optical devices to provide reliable fiber connectivity in data centers, wiring closets and campus networks. The small form factor enables easy deployment and replacement without powering down equipment.
Advantages
This SFP transceiver provides stable gigabit performance with low power consumption and a compact, hot-pluggable design that simplifies maintenance. Compatible with standard SFP interfaces, it enables quick installation and hot-swap replacement to minimize network downtime. The module is optimized for multimode fiber links at 850 nm, making it suitable for cost-effective short-distance connections while maintaining signal integrity and interoperability with a wide range of networking equipment.
Suitable for
 Short-range gigabit Ethernet links within data centers
 Campus and enterprise network fiber runs
 Telecom closets and wiring cabinets requiring multimode connectivity
 Upgrading switches and routers with SFP ports for fiber connectivity
Key specifications
 Standard: 1000BASE-SX gigabit Ethernet over multimode fiber
 Wavelength: 850 nm
 Form factor: Small Form-factor Pluggable (SFP), hot-pluggable
 Fiber type: Multimode fiber (MMF)
 Typical reach: short-range multimode links (dependent on fiber grade and link budget)
 Interface: SFP optical port for single optical lane
How to use
Install the module by inserting it into an available SFP slot on compatible network equipment until it seats firmly and the retention mechanism engages. Connect a multimode fiber patch cord (with appropriate connectors) to the module’s optical port, ensuring correct polarity and secure connections. After installation, configure the device’s network settings as required; the module supports hot-plug operation so the host can detect and initialize the link without a system shutdown. Verify link status and perform any necessary diagnostics using the host device management interfaces.
Usage recommendations
Use the module with multimode fiber of appropriate grade (e.g., OM1/OM2/OM3/OM4) and matched patch cords to achieve the expected short-range performance. Keep connector end-faces clean and protected when not connected, and follow standard electrostatic discharge (ESD) precautions during handling. For reliable operation, verify compatibility with the host equipment’s SFP port and consult link budget calculations to confirm reach for your specific fiber type and installation environment.
