## Long description

CBO ALL4756 1000Base-SX is a fiber optic SFP transceiver module designed for gigabit Ethernet over multimode fiber. The module supports 1000Base-SX operation and is hot-pluggable for installation in compatible SFP ports on switches, routers and servers. It provides short-range fiber connectivity for link extensions, replacements or network upgrades while maintaining standard electrical and optical interfaces for straight-forward interoperability.
Advantages
The transceiver offers compact SFP form factor compatibility and hot-swap capability to minimise downtime during installation or replacement. It is engineered for multimode fiber to deliver reliable short-range gigabit links with standard-compliant optical signalling. Its straightforward electrical and optical interfaces ensure broad compatibility with equipment that supports standard SFP modules.
Suitable for
Short-range gigabit Ethernet links over multimode fiber within data centres and wiring closets
Adding or replacing fiber ports on switches and routers with SFP slots
Server uplinks and aggregation in small to medium enterprise networks
Network maintenance and staged upgrades where hot-pluggable modules are required
Key specifications
Interface: Small Form-Factor Pluggable (SFP), hot-pluggable
Data rate: 1 Gbps (1000Base-SX)
Optical medium: Multimode fiber (MMF)
Transmission wavelength: shortwave multimode optics (typically 850 nm class)
Typical reach: short-range multimode distances, dependent on fiber type and modal bandwidth
Compatibility: Standard SFP host ports in switches, routers and servers that support 1000Base-SX modules
How to use
Insert the SFP transceiver into an empty compatible SFP slot on the powered equipment until it clicks into place. Connect the multimode fiber patch cord to the transceiver’s fiber port, ensuring correct connector type and polarity. After installation, verify link status and speed on the host device and use appropriate network management tools to confirm optical parameters and connectivity. For module removal, disengage the retention mechanism and pull the transceiver straight out while observing electrostatic discharge precautions.
Usage recommendations
Use multimode fiber patch cords and connectors that match the transceiver’s specifications and the host equipment’s port type. Observe ESD precautions during handling, avoid bending fiber below recommended radius, and verify reach against installed fiber’s modal bandwidth and link budget before deployment.
