SFP transceiver CBO SFP-1G-MMF-2KM 1G 850 nm multimode fiber, up to 2 km

CBO SFP-1G-MMF-2KM is a small form-factor pluggable (SFP) optical transceiver that provides 1 Gbps full-duplex data transmission over multimode fiber at an 850 nm wavelength. Intended for short-range fiber links up to 2 km, this module plugs into standard SFP ports for hot-swappable installation without powering down network equipment. The transceiver is suitable for use in switches, routers and media converters where reliable 1G multimode connectivity is required in enterprise LANs, campus networks and data center access layers.

Advantages

The transceiver delivers predictable 1 Gbps performance over multimode links and supports straightforward interoperability with devices that accept standard SFP optical modules. Its hot-pluggable SFP form factor simplifies upgrades and maintenance by allowing replacement without interruption to power. Optimized for short-range fiber, the module reduces electromagnetic interference compared with copper links and enables extended reach beyond typical copper cabling limits.

Suitable for

• 1 Gigabit Ethernet uplinks and access links on switches and routers
• Fiber connections between buildings on a campus over multimode fiber
• Media converter fiber ports converting copper to multimode fiber
• Access layer connections in data centers and wiring closets

Key specifications

• Data rate: 1 Gbps (full duplex)
• Optical wavelength: 850 nm
• Fiber type: multimode fiber (MMF)
• Maximum link distance: up to 2 km (depending on fiber type and link budget)
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Connector type: LC duplex compatible

How to use

Insert the SFP transceiver into an empty SFP slot on compatible network equipment until it engages securely; avoid forcing the module. Connect LC duplex multimode fiber patch cables following correct transmit/receive orientation. Ensure connected devices are configured for 1 Gbps operation and that fiber type and link distance are within the module's supported range. Monitor link status LEDs on the host device to confirm successful negotiation and link activity.

Recommendations

Use multimode fiber of suitable grade (OM1/OM2/OM3/OM4) and verify end-to-end cleanliness of connectors to maintain optimal optical performance. For maximum reach, calculate link loss and ensure patch panels and connectors do not exceed the allowed insertion loss. Replace or reseat modules only when required and follow ESD precautions when handling the transceiver.
