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

CBO SFP-1G-ZX-160KM-CO-BO is a small form-factor pluggable (SFP) optical transceiver for single-mode fiber that supports a 1.25 Gbit/s data rate and uses an LC duplex connector. Engineered for long-reach applications, this ZX-class module enables reliable optical links up to 160 km, making it suitable for telecoms, carrier networks, metro rings and long-distance enterprise connections. The compact, hot-swappable design allows straightforward installation in switches, routers and optical equipment that accept SFP modules.

Advantages

The module delivers stable 1.25 Gbit/s transmission over single-mode fiber with a wavelength optimized for long-distance links, offering low power consumption and compact SFP form factor for high-density setups. Its hot-pluggable design reduces downtime during upgrades or replacements, while standardized LC interfaces ensure broad compatibility with network hardware. Built to support extended reach, the transceiver reduces the need for intermediate amplifiers or regenerators in many long-haul scenarios.

Suitable for

• Long-distance fiber uplinks between sites and data centers
• Carrier and telecom backbone links and metro ring segments
• Enterprise point-to-point connections over single-mode fiber
• Network equipment requiring 1 Gbit/s SFP modules with LC interfaces

Key specifications

• Data rate: 1.25 Gbit/s
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 160 km (ZX-class)
• Connector type: LC duplex
• Form factor: SFP (small form-factor pluggable), hot-swappable
• Typical power consumption: low-power SFP class (device-dependent)

How to use

Install the SFP module into an SFP slot on a compatible switch, router or optical device while the host equipment is powered on or off according to the vendor’s guidance. Connect LC duplex single-mode patch cords to the module, observing correct TX/RX orientation. Verify link status and configure the host port for 1 Gbit/s operation if manual configuration is required. For long-reach links, ensure appropriate fiber quality, proper attenuation and that end equipment supports the required optical budgets.

Recommendations

Use certified single-mode LC patch cords and inspect fiber connectors before installation to minimize signal loss. For links approaching the maximum reach, confirm optical budget and consider dispersion and splicing losses. Maintain proper electrostatic discharge (ESD) precautions when handling the transceiver and follow equipment vendor guidelines for compatibility and firmware settings.
