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

CBO SFP-1G-ZX-160KM-MR-BO is a Small Form-factor Pluggable (SFP) optical transceiver module designed for single-mode fiber links requiring long reach. The module supports a 1.25 Gbit/s data rate and operates at the ZX wavelength (around 1550 nm) with an LC duplex connector, enabling fiber spans up to 160 km under appropriate link conditions. It is intended for use in telecom, carrier-grade and enterprise network uplinks where stable long-distance optical transmission is required.

Advantages

This SFP transceiver provides a standardized, hot-pluggable interface for 1 Gbit/s ports and offers long-reach capability to 160 km without intermediate amplification in suitable link designs. The single-mode design and LC connector ensure compatibility with common single-mode patching and fiber infrastructure. The compact SFP form factor minimizes space usage in switches and routers while allowing easy replacement or upgrade of optical interfaces.

Suitable for

• Long-distance optical uplinks between sites and data centers
• Carrier and metro access links requiring ZX (1550 nm) optics
• Enterprise WAN connections over single-mode fiber
• Network equipment with SFP ports (switches, routers, media converters)

Key specifications

• Data rate: 1.25 Gbit/s (SFP Fast Ethernet/1G support)
• Fiber type: Single-mode fiber (SMF)
• Wavelength: ZX-class (~1550 nm)
• Connector: LC duplex
• Maximum reach: up to 160 km (link-dependent)
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Optical interface: simplex/duplex single-mode transmit/receive

How to use

Insert the SFP transceiver into an appropriate SFP socket on a switch, router or media converter while the device is powered on or off according to the host equipment manual. Connect LC single-mode patch cables to the transmit and receive ports, observing correct polarity. Verify that the host port is configured for 1 Gbit/s operation and check link status LEDs or device diagnostics to confirm a stable connection. For maximum reach, ensure fiber attenuation, connector quality and chromatic dispersion are within acceptable limits for ZX-class optics.

Recommendations

Use this module with single-mode fiber and LC connectors only. When planning links near the 160 km range, perform end-to-end optical power budget calculations and consider dispersion and connector/splice losses. Store and handle transceivers with protective caps fitted to the optical ports to avoid contamination. Follow host vendor guidance for compatibility and supported optical parameters.
