SFP Network Transceiver Module CBO ET4201-ZX-BO 1250 Mbit/s 1550 nm single-mode

The SFP Network Transceiver Module CBO ET4201-ZX-BO 1250 Mbit/s 1550 nm single-mode is a hot-pluggable small form-factor pluggable (SFP) optical transceiver designed for serial data transmission over long-reach single-mode fiber at a wavelength of 1550 nm. It provides a 1250 Mbit/s data rate and is intended for establishing optical links between switches, routers and other network equipment in metropolitan and long-distance backbone networks. The compact SFP form factor enables easy installation, replacement or upgrade without powering down compatible equipment.

Advantages

This transceiver supports long-distance single-mode transmission at 1550 nm and a serial data rate of 1250 Mbit/s, offering a balance of reach and data throughput suitable for backbone connections. The hot-pluggable SFP design reduces maintenance time and allows in-service replacement. Compact dimensions make it compatible with a wide range of SFP ports in switches and routers, while standardized optical interfaces simplify interoperability with single-mode fiber infrastructure.

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or optical equipment while the device is powered according to the manufacturer's hot-swap guidelines. Connect single-mode fiber with the appropriate connectors and ensure fiber polarity and connector cleanliness. Configure the connected network ports on your devices to the required link settings and verify link status through device LEDs or management interfaces. Follow standard safety and handling practices for optical transceivers to avoid damaging the fiber or the transceiver.

Recommendations

Use this module in single-mode fiber links where long reach is required; verify compatibility with the host device's SFP interface and firmware. Clean fiber connectors before insertion, observe ESD precautions when handling the module, and confirm link parameters in the network equipment to ensure stable operation.
