## Summary description

CBO ET4204-BX10D is a fiber optic transceiver operating at 1310 nm with a transmission range of up to 10 km. Designed for single-mode fiber links, it enables reliable data transport between network devices, switches or media converters. Suitable for telecom and enterprise networks where medium-distance optical connectivity and stable link performance are required.

## Long description

CBO ET4204-BX10D 1310nm 10 km is a single-mode fiber optic transceiver designed for medium-distance optical links. Operating at a central wavelength of 1310 nm, the module supports reliable data transport over distances up to 10 km and is suitable for connecting switches, routers or media converters in telecom and enterprise networks. The transceiver implements industry-standard optical interfaces and is intended for use in systems that require stable single-fiber or duplex single-mode connectivity.
Advantages
The transceiver provides predictable optical performance with a specified reach of up to 10 km on single-mode fiber at 1310 nm, enabling consistent link budgets for network planning. Its compact form factor and standardized interface facilitate easy installation into compatible network equipment. Designed for continuous operation in network environments, the module offers low power consumption and is compatible with common SFP/SFP+ cages and ports used in switches and media converters.
Suitable for
Point-to-point fiber links between switches or routers within campus, enterprise or ISP access networks
Connecting media converters to extend copper-based devices over fiber
Telecom aggregation and distribution links requiring 10 km reach on single-mode fiber
Key specifications
Optical wavelength: 1310 nm
Maximum transmission distance: up to 10 km on single-mode fiber (SMF)
Fiber type: single-mode fiber (SMF)
Form factor: compact SFP-style transceiver module
Interface type: optical duplex or single-fiber depending on application
Typical power consumption: low-profile design suitable for continuous operation
How to use
Install the transceiver into a compatible SFP slot on your switch, router or media converter, ensuring the device is powered down or the slot supports hot-plug insertion per the host device documentation. Connect single-mode fiber using appropriate LC or compatible connectors, observing correct transmit/receive orientation. Verify link status and signal levels via the host device interface or management tools. For optimal performance, use quality single-mode fiber and clean connectors before mating.
Usage recommendations
When deploying this 1310 nm transceiver for links approaching the 10 km limit, perform an optical loss budget calculation and consider fiber attenuation, connector and splice losses. Use certified single-mode patch cords and maintain connector cleanliness to ensure stable operation. Check host device compatibility with SFP-style modules and follow ESD precautions during handling and installation.
