## Summary description

SFP network transceiver module CBO ET4201-ZX-BO provides 1250 Mbit/s serial data transmission for long-reach single-mode fiber at 1550 nm. Designed for hot-pluggable insertion into SFP ports, it supports link establishment between switches, routers and optical equipment. Use cases include metropolitan and long-distance backbone links; benefits include compact form factor and straightforward replacement or upgrade.

## Long description

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.
Suitable for
 Metropolitan area network trunk and aggregation links
 Long-distance backbone connections between sites
 Interconnecting routers and switches with single-mode fiber
 Upgrading existing SFP ports to 1550 nm long-reach capability
