Fiber optic SFP module CBO SFP-1G-ZX-120KM-IB-BO, 1 Gbit/s, LC, ZX, up to 120 km

The BlueOptics fiber optic SFP module SFP-1G-ZX-120KM-IB-BO is a single‑mode, single‑fiber 1 Gbit/s transceiver with an LC connector and ZX long‑reach optics. Designed for point‑to‑point links up to 120 km, this compact, hot‑pluggable SFP form factor fits standard SFP ports in switches, routers and media converters to enable long‑distance fiber backbone connections and WAN links. The module supports single‑fiber operation with a wavelength and power budget suited to carrier and service provider networks that require stable, single‑mode transmission over extended distances.

Advantages

The module offers a 1 Gbit/s data rate in a small, hot‑swappable SFP package that simplifies installation and replacement without powering down equipment. ZX optics enable extended reach up to 120 km on single‑mode fiber, reducing the need for intermediate amplifiers or repeaters in many deployments. The LC connector ensures compact fiber cabling and compatibility with a wide range of network devices that accept SFP transceivers.

Suitable for

• Long‑distance backbone links between sites or data centers
• WAN and metropolitan area network (MAN) connections
• Carrier and service provider fiber segments requiring single‑mode ZX optics
• Upgrading switches or routers with SFP ports for extended reach

Key specifications

• Data rate: 1 Gbit/s
• Fiber type: single‑mode (single fiber operation)
• Connector: LC
• Optical range class: ZX (long reach)
• Maximum link distance: up to 120 km
• Form factor: SFP (hot‑pluggable)

How to use

Insert the SFP module into an empty SFP port on a compatible switch, router or media converter while the host device is powered on if hot‑swap is supported. Connect the LC terminated single‑mode fiber cable to the transceiver, ensuring correct orientation and clean endfaces to prevent signal loss. Configure the host device interface for 1 Gbit/s operation if necessary and verify link status and optical parameters through device diagnostics or network management tools. Follow the equipment manufacturer’s guidance for any vendor compatibility settings.

Recommendations

Use high‑quality, single‑mode fiber with appropriate connectors and maintain clean fiber endfaces. Verify link budget and dispersion for routes approaching the 120 km limit and consider intermediate amplification or alternative modules if margins are insufficient.
