Description
The Cisco CPAK-100G-CWDM4 is a high-performance 100 Gigabit Ethernet transceiver module designed for data center and enterprise core networking environments. Built in the compact CPAK form factor, it supports the CWDM4 MSA standard, enabling transmission over duplex single-mode fiber (SMF) with a reach of up to 2 kilometers. This module utilizes four wavelengths on the 1271–1331 nm CWDM grid, multiplexed into a single fiber pair, significantly reducing cabling complexity. Its energy-efficient design consumes less power compared to traditional transceiver formats, making it ideal for high-density deployments.
Equipped with an MPO-12 connector, the CPAK-100G-CWDM4 integrates seamlessly into existing fiber infrastructures while delivering reliable 100G connectivity. It features digital optical monitoring (DOM) for real-time diagnostics, including temperature, optical power, and voltage levels. The module supports error correction via FEC (Forward Error Correction) and operates at a nominal data rate of 103.125 Gbps. When purchasing used, buyers should confirm optical clarity, connector integrity, and DOM functionality to ensure optimal performance in refurbished network environments.
