Fiber optic modem CBO JD102B-BO SFP LC 100 Mbit/s 2000 m

CBO JD102B-BO is a fiber optic SFP LC module engineered to provide stable 100 Mbit/s Ethernet transmission over single-mode fiber up to 2000 m. Designed for use in devices with standard SFP slots, this compact transceiver enables point-to-point fiber links and media conversion between copper and fiber-based network equipment. The module is suitable for network links between buildings, telecom equipment interconnection, and industrial networks that require extended reach and consistent data transfer.

Advantages

The module delivers a predictable 100 Mbit/s link over long single-mode fiber runs, supporting distances up to 2000 m with an LC connector interface. Its SFP form factor ensures compatibility with a wide range of switches, routers and media converters that accept SFP transceivers. The compact design reduces rack space usage and simplifies field installation while providing electrical isolation and immunity to electromagnetic interference inherent to fiber connections.

How to use

Install the module into a compatible SFP slot on a switch, router or media converter while the device is powered down or following the manufacturer's hot-swap guidance. Connect a single-mode fiber cable with LC connectors to the module and secure the opposite end to the corresponding transceiver. Configure the network device for a 100 Mbit/s link if manual speed settings are required; otherwise most equipment will negotiate the link automatically. Verify link status and test throughput after installation to confirm correct operation.

Recommendations

Use single-mode fiber with appropriate attenuation and connector cleanliness to achieve reliable operation at the specified 2000 m distance. Avoid bending the fiber beyond recommended radii and ensure SFP compatibility with the host device. For long-term stability, perform periodic link checks and keep the transceiver and fiber endfaces free from dust and contamination.
