Cisco ONS-SE-GE-ZX

The Cisco ONS-SE-GE-ZX is a Small Form-Factor Pluggable (SFP) transceiver module manufactured by Cisco Systems. It is designed for use in Cisco optical networking solutions, specifically in the Cisco ONS (Optical Network System) platform. The "SE" in the model name stands for "Single-Ended," indicating that it is a single-ended transceiver module. "GE" stands for "Gigabit Ethernet," indicating that it supports Gigabit Ethernet connectivity. "ZX" stands for "Zero Dispersion Shifted," which refers to the type of optical fiber it is compatible with. The Cisco ONS-SE-GE-ZX SFP transceiver module operates over a single-mode fiber optic cable and supports a maximum transmission distance of up to 70 kilometers (43.5 miles). It uses a wavelength of 1550 nanometers (nm) and supports data rates of up to 1.25 Gbps (Gigabits per second). Overall, the Cisco ONS-SE-GE-ZX is used in optical networking applications to provide long-distance Gigabit Ethernet connectivity over single-mode fiber optic cables.
