CBO SFP transceiver SFP-1G-ZX compatible module — single‑mode 1.25Gb/s, long‑reach

Compatible CBO SFP transceiver SFP-1G-ZX is a single‑mode SFP module that supports 1.25 Gb/s data rates and provides long‑reach optical connectivity for network equipment with SFP ports. The module is compact and hot‑pluggable, allowing installation in switches, routers and media converters without powering down devices. Designed for links requiring ZX optics, it extends fiber connections over long distances while maintaining industry‑standard form factor and interoperability with common networking hardware.

Advantages

This CBO SFP transceiver offers long‑reach performance in a small, hot‑swappable module. It supports single‑mode fiber at 1.25 Gb/s, enabling extended link distances with stable optical transmission. The device follows standard SFP form factor and electrical interfaces, which helps ensure compatibility with a wide range of network equipment. Its compact design simplifies rackspace use and maintenance tasks.

Suitable for

• Long‑distance single‑mode fiber links between switches and routers
• Core-to-distribution or distribution-to-access uplinks in campus and enterprise networks
• Media converters and small form‑factor network devices requiring ZX optics
• Network upgrades where replaceable, hot‑pluggable optics are needed

Key specifications

• Optical type: single‑mode (SMF)
• Data rate: 1.25 Gb/s (SFP 1G)
• Link reach: long‑reach ZX class optics (for extended single‑mode distances)
• Form factor: SFP (small form‑factor pluggable), hot‑pluggable
• Connector: LC duplex optical connector
• Transmission media: single‑mode fiber
• Temperature range: industrial/operational range appropriate for standard SFP modules

How to use

Install the SFP‑1G‑ZX module into an available SFP port on a compatible switch, router or media converter while the host device is powered on, taking standard electrostatic discharge precautions. Connect single‑mode fiber cables with LC duplex connectors to the module, observing correct transmit/receive orientation. After insertion and cable connection, verify link status and negotiate 1.25 Gb/s operation via the host device interface. If necessary, consult the host equipment documentation to confirm compatibility and any required configuration changes for optical ports.

Recommendations

Use high‑quality single‑mode fiber and clean LC connectors to maintain signal integrity. Verify distance and loss budget when planning long‑reach links and ensure transceiver and remote optics use compatible ZX wavelength and power classes. For installations in dusty or harsh environments, protect connectors with dust caps when unused and perform regular inspections to avoid contamination that can degrade optical performance.
