Fiber optic SFP module CBO SFP-1G-ZX-160KM-DL-BO 1.25 Gbit/s LC single-mode 160 km

CBO SFP-1G-ZX-160KM-DL-BO is a fiber optic SFP transceiver module that supports a 1.25 Gbit/s data rate over single-mode fiber. Fitted with an LC duplex connector, it is intended for long-distance links up to 160 km and is compatible with standard SFP ports. The module delivers duplex transmission for Gigabit Ethernet and telecom applications and installs with a plug-and-play approach for uplinks, backbone extensions and long-reach connections between sites.

Advantages

This SFP transceiver offers long-reach single-mode performance up to 160 km while maintaining the compact SFP form factor for compatibility with a wide range of network equipment. It supports a 1.25 Gbit/s line rate and duplex communication via LC connectors, enabling straightforward integration into existing fiber networks. The module has a hot-pluggable design for minimal downtime during replacement or upgrades and follows industry form-factor and optical interface conventions for reliable operation in networking and telecom environments.

Suitable for

• Long-distance Gigabit Ethernet uplinks between switches and routers
• Telecom links and metro network connections requiring single-mode fiber
• Data center inter-site connectivity and backbone extensions
• Enterprise campus links where distances exceed typical multimode range

Key specifications

• Data rate: 1.25 Gbit/s
• Fiber type: single-mode
• Maximum reach: up to 160 km
• Connector type: LC duplex
• Form factor: Small Form-factor Pluggable (SFP)
• Transmission mode: duplex

How to use

Install the module into an SFP slot on a compatible switch, router or transponder by aligning the module with the slot and inserting until it locks; handle the optical interfaces by keeping dust caps on until ready to connect. After insertion, connect LC-terminated single-mode fiber patch cables to the transmit and receive ports following the equipment documentation for cable routing and polarity. Confirm link status via the host device management interface and verify optical power and error statistics if required. For removal, power down or follow hot-swap procedures specified by the host device, then depress the release latch and extract the module.

Recommendations

Store and handle the transceiver in a dry, clean environment and avoid touching the optical endfaces. Use single-mode fiber with appropriate attenuation planning for long spans and perform optical power budget calculations when planning links near the maximum reach. Ensure network equipment supports the SFP optical characteristics and configure link settings on the host device as needed for stable operation.
