SFP Transceiver CBO SFP-SX-I 850nm 550m — multimode optical module

CBO SFP-SX-I 850nm 550m is a small form-factor pluggable (SFP) multimode fiber optical transceiver that operates at an 850 nm wavelength and supports link distances up to 550 meters over suitable multimode fiber. The module is intended for short-range Ethernet and fibre connections and is compatible with standard SFP slots. It supports hot-swap installation, enabling quick replacement or addition without powering down the host device, and provides a compact, modular interface for switches, servers and media converters in local networks and data center environments.

Advantages

The transceiver offers a standardized SFP form factor for broad compatibility with networking equipment and straightforward hot-pluggable installation. Its 850 nm VCSEL-based optical design provides reliable short-reach multimode connectivity with low power consumption and compact physical dimensions that save rack space. The module is designed for plug-and-play use and supports common Ethernet applications where multimode fiber runs are required.

Suitable for

• Short-range Ethernet links within campus and enterprise networks
• Connections between switches, routers and servers in data closets and wiring rooms
• Media converters and modular transceiver slots in network devices

Key specifications

• Optical wavelength: 850 nm
• Maximum reach: up to 550 m over multimode fiber (depending on fiber type and channel conditions)
• Form factor: SFP (Small Form-factor Pluggable)
• Fiber type: Multimode fiber (MMF)
• Interface: Duplex LC connector
• Hot-swappable: Yes
• Typical power consumption: low (device-specific values depend on host)
• Application: Short-range Ethernet and fibre links

How to use

Insert the SFP module into a compatible SFP port on a switch, router, server or media converter until it seats firmly and the latch engages. Connect a duplex LC-terminated multimode fiber patch cable to the module’s connector, observing proper transmit/receive orientation. Configure the host device as required for the desired Ethernet port speed and duplex settings; many networks will autodetect link parameters. The module supports hot-swap replacement—remove and install modules while the host is powered on, following standard ESD precautions.

Usage recommendations

Use OM3/OM4 multimode fiber for best reach and performance up to the specified distance, and verify fiber certification and cleanliness before connection. Observe ESD handling procedures when installing or removing the module, and ensure the host device firmware supports third-party SFP modules where required.
