SFP fiber transceiver CBO SFP-1G-ZX-160KM-NV-BO 1.25 Gbps 160 km single‑mode 1310/1550 nm

The SFP fiber transceiver CBO SFP-1G-ZX-160KM-NV-BO is a single‑mode optical module that supports a 1.25 Gbps data rate for long‑reach links up to 160 km. Designed to fit standard SFP ports, this transceiver provides duplex optical connectivity for network equipment such as switches, routers and media converters. It operates on 1310/1550 nm wavelengths and is intended for stable point‑to‑point transmission in telecom and enterprise backbone environments.

Advantages

This SFP transceiver offers long‑distance transmission capability up to 160 km while maintaining a 1.25 Gbps data rate, enabling cost‑effective extension of fiber links without changing existing SFP interfaces. Its single‑mode design and standard SFP form factor ensure compatibility with a wide range of networking devices. The use of defined transmit and receive wavelengths supports low latency and reliable optical signal transport over metropolitan and long‑haul connections.

Suitable for

• Long‑reach backbone links between buildings or data centers
• Telecom trunk lines and carrier networks
• Enterprise WAN and campus connections requiring single‑mode fiber
• Media converters and legacy devices with SFP ports

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single‑mode
• Maximum reach: up to 160 km
• Wavelengths: 1310 nm (Tx) / 1550 nm (Rx)
• Form factor: standard SFP (small form‑factor pluggable)
• Interface: duplex optical

How to use

Insert the transceiver into a compatible SFP port on your switch, router or media converter until it locks into place. Connect single‑mode fiber patch cords to the transmit and receive ports using appropriate LC connectors and ensure correct polarity. Verify link status via the host device LEDs or management interface and configure interface settings (speed, duplex, and any relevant optical alarms) according to network requirements. Follow device vendor guidance for hot‑swap and ESD precautions during installation.

Recommendations

Use this module with single‑mode fiber rated for long‑reach applications and with compatible networking equipment that supports 1.25 Gbps SFP transceivers. Confirm fiber attenuation and margin for the full 160 km span, and consider in‑line amplification or dispersion management only if required by link budget calculations.
