SFP transceiver CBO SFP-1G-ZX Arista compatible, 1 Gbps, single-mode fiber, up to 80 km

CBO SFP-1G-ZX is an SFP-form-factor optical transceiver providing 1 Gbps data transfer over single-mode fiber for distances up to 80 km. Compatible with Arista equipment, this module supports standard 1000BASE-ZX links and installs in SFP slots on switches and routers. The hot-pluggable design enables insertion and removal without powering down the host device, and the transceiver follows common optical parameters for long-reach metropolitan and inter-building fiber connections.

Advantages

This compact SFP module delivers 1 Gbps single-mode connectivity with extended reach, allowing network links across campuses and between distant facilities. Compatibility with Arista equipment simplifies deployment in mixed-vendor environments. The SFP form factor provides flexible port usage and easy replacement or upgrade, while hot-pluggable operation minimizes service interruption during installation or maintenance.

Suitable for

• Long-distance campus backbone links
• Metro and carrier access connections
• Inter-building fiber runs on single-mode infrastructure
• 1 Gbps uplinks and aggregation ports on switches and routers

Key specifications

• Data rate: 1 Gbps (1000BASE-ZX)
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 80 km
• Form factor: SFP (Small Form-factor Pluggable)
• Connector type: LC duplex
• Wavelength: long wavelength (typical for ZX-class transceivers)
• Power: low-power, SFP-compliant electrical interface

How to use

Insert the CBO SFP-1G-ZX module into an available SFP port on an Arista-compatible switch or router until it clicks into place. Connect LC duplex single-mode fiber patch cords to the module’s optical ports, ensuring correct transmit/receive orientation. Configure the host interface for 1 Gbps operation if required by the device; many platforms will auto-negotiate the link. Monitor link status via the device management interface to confirm optical signal presence and proper operation.

Recommendations

Verify end-to-end single-mode fiber quality and clean connectors before installation to prevent signal loss. Use appropriate optical loss budget calculations for links approaching the 80 km range and consider in-line amplification or dispersion compensation only if specified by the network design. Follow equipment vendor guidance for compatibility and firmware requirements when deploying third-party transceivers in Arista-compatible hardware.
