SFP fiber transceiver CBO Zyxel SFP-1G-MMF-2KM 1G multimode 2 km

The SFP fiber transceiver CBO Zyxel SFP-1G-MMF-2KM 1G multimode 2 km is a hot-pluggable Small Form-factor Pluggable (SFP) optical module designed for short-range multimode fiber links. It supports a 1 Gbps data rate over multimode fiber for distances up to 2 km, making it suitable for connections between switches, routers and other network devices in enterprise and campus environments. The module adheres to the standard SFP form factor to provide straightforward upgrades and replacements without modifying existing hardware.

Advantages

This SFP transceiver offers compatible multimode fiber connectivity with a 1 Gbps throughput and a link reach up to 2 km. Its hot-pluggable design allows replacement or installation without powering down the host device, minimizing downtime. The compact SFP form factor ensures broad compatibility with a wide range of networking equipment, while the optical interface provides low-latency, electrically isolated connections that reduce susceptibility to electromagnetic interference.

Suitable for

• Short-distance trunking between switches in enterprise LANs and campus networks
• Fiber uplinks for access switches and aggregation devices
• Replacing or upgrading SFP ports in routers, switches and media converters
• Network segments requiring galvanic isolation or reduced EMI

Key specifications

• Data rate: 1 Gbps
• Fiber type: Multimode fiber
• Maximum reach: Up to 2 km over multimode fiber
• Form factor: SFP (hot-pluggable)
• Interface: Optical

How to use

Insert the SFP transceiver into an compatible SFP slot on your switch, router or media converter until it latches. Connect a compatible multimode fiber patch cable to the module’s optical port, ensuring proper connector type and polarity. After insertion and connection, the host device should detect the module and negotiate link parameters automatically. Follow device-specific configuration steps if VLANs, link aggregation or speed/duplex settings need to be adjusted.

Recommendations

Use multimode fiber patch cables rated for the intended distance and maintain clean connectors to ensure optimal signal quality. Verify compatibility with the host device and, if available, consult the equipment’s list of supported transceivers. Avoid excessive bending of fiber cables and operate the transceiver within recommended temperature and environmental ranges for reliable performance.
