SFP transceiver CBO SFP-1G-ZX 1G single‑mode 80 km

The CBO SFP-1G-ZX 1G single‑mode SFP transceiver is a fibre-optic module designed for long-reach point-to-point connections up to 80 km. Built in the SFP form factor, it supports 1 Gbps data rates and provides a standardized interface for network switches, routers and optical equipment that accept SFP modules. The module is intended for single-mode fiber deployment and offers stable optical transmission for WAN links, campus backbones and data centre interconnects.

Advantages

This SFP transceiver supports standard 1 Gbps operation in a compact SFP package suitable for hot-swappable use in compatible ports. It is optimised for long-distance single-mode fibre links up to 80 km, reducing the need for intermediate repeaters or amplifiers. The module follows established optical signalling parameters for interoperability with common networking equipment, helping ensure predictable performance in metropolitan and wide-area deployments.

Suitable for

• Long-reach single-mode fibre links between buildings, campuses or sites
• WAN aggregation and metro network connections
• Data centre interconnects and server-to-switch uplinks over fibre
• Network equipment upgrades requiring SFP form factor and 1 Gbps speed

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet / 1x SFP compatible)
• Optical mode: single-mode fiber
• Maximum link distance: up to 80 km (single-mode, unobstructed)
• Form factor: SFP (hot-pluggable)
• Wavelength: long‑reach optical band characteristic for ZX-class modules
• Connector type: LC duplex
• Typical application: long-distance fibre links for WAN, metro and data centre use

How to use

Insert the SFP-1G-ZX transceiver into an SFP slot on a compatible network device until it seats firmly; then connect single-mode LC duplex fibre patch cords to the module’s ports, observing Tx/Rx orientation. Ensure the connected device is configured for 1 Gbps operation and that fiber end faces and connectors are clean to prevent signal loss. Verify link status on the network equipment and monitor optical power and error counters where available to confirm a stable connection.

Recommendations

Use certified single-mode duplex fibre and LC connectors, keep connectors and fibre endfaces free of dust, and follow the host equipment’s guidance on supported SFP modules. For links approaching the maximum 80 km, verify optical loss budget and consider using suitable optical amplifiers or dispersion compensation only if required by the specific link characteristics.
