## Summary description

CBO SFP-3111 is a fiber optic SFP transceiver supporting 1000Base-SX for Gigabit Ethernet over multimode fiber. Designed for short-range links in switches, routers and network equipment, it provides hot-pluggable SFP form factor, standard optical interface and compatibility with 1 Gbps ports. Use it to extend or replace short-distance fiber connections in local networks.

## Long description

CBO SFP-3111 is a fiber optic SFP transceiver module that supports 1000Base-SX for short-range Gigabit Ethernet over multimode fiber. It is supplied in a hot-pluggable Small Form-factor Pluggable (SFP) package and is intended for use in switches, routers and other network devices with 1 Gbps ports. The module provides a standard optical interface for short-distance links in local area networks, allowing replacement or extension of multimode fiber connections without changes to host equipment.
Advantages
The transceiver offers a compact hot-swappable design that simplifies installation and maintenance on active network equipment. Its compliance with 1000Base-SX optical parameters ensures interoperability with compatible multimode fiber infrastructure. The module supports standard SFP insertion and removal procedures, minimizing downtime when upgrading or replacing links. Energy consumption and heat output are appropriate for rack-mounted and small-form network devices, and the standardized connector provides reliable physical and optical coupling.
Suitable for
 Short-range Gigabit Ethernet links over multimode fiber in campus and office networks
 Upgrading 1 Gbps ports on switches and routers to fiber connections
 Replacing failed multimode fiber transceivers in network equipment
 Connecting fiber patch panels and short-distance backbone segments within buildings
Key specifications
 Data rate: 1 Gbps (1000Base-SX)
 Fiber type: multimode fiber (MMF)
 Form factor: SFP (hot-pluggable)
 Wavelength range: suitable for short-range multimode operation (850 nm class)
 Typical reach: short-range links (distance depends on fiber type and modal bandwidth)
 Connector type: standard duplex optical connector
How to use
Power down is generally not required; insert the SFP transceiver into an empty SFP port on a compatible switch, router or media converter until it seats securely. Connect multimode fiber patch cords to the transceiver's duplex optical connector, ensuring correct transmit/receive orientation. Configure the host port to 1 Gbps operation if necessary and verify link status through the device management interface or status LEDs. To remove, follow the host equipment's hot-swap procedures and gently extract the module by its housing.
Usage recommendations
Use suitable multimode fiber and matching patch cords rated for short-range Gigabit links; verify fiber type (OM1/OM2/OM3/OM4) and expected reach. Keep optical contacts clean and protected with dust caps when not connected. Confirm compatibility with the host device and its supported SFP modules before installation to ensure proper link operation.
