CPAK-100G-LR4 Cisco 100GBase-LR4 CPAK Transceiver Module 100Gbps over SMF

SEO Meta Description:

Discover the incredible capabilities of the CPAK-100G-LR4 Cisco 100GBase-LR4 CPAK Transceiver Module, providing lightning-fast 100Gbps over Single-Mode Fiber (SMF). Learn everything you need to know about this advanced networking technology.


In the world of networking, speed and reliability are paramount. One technology that has been making waves in this field is the CPAK-100G-LR4 Cisco 100GBase-LR4 CPAK Transceiver Module. Offering an impressive 100Gbps over Single-Mode Fiber (SMF), this module is changing the game. In this comprehensive article, we will delve into the details of this revolutionary technology, covering everything from its features and benefits to installation and FAQs.

The Power of CPAK-100G-LR4 Cisco 100GBase-LR4 CPAK Transceiver Module

The primary function of the Cisco CPAK-100G-LR4 and CPAK-100GE-LR4 modules is to enable 100Gbps optical connections over conventional Single-Mode Fiber (SMF, G.652) terminated with either SC connectors (as shown in Figure 1) or LC connectors (as depicted in Figure 2). It’s worth noting that the LC-SC adapter on the CPAK-100G-LR4 can be removed if you prefer LC connectors over the default SC connectors; however, SC connectors are the officially recommended and supported connector type.

The LR4 module complies with IEEE 802.3ba standards and is capable of supporting link distances of up to 10 kilometers over standard SMF, G.652. It accomplishes this by transmitting an aggregate data signal of 100 Gbps, which is distributed across four LAN Wavelength-Division Multiplexing (WDM) wavelengths, each operating at a nominal rate of 25 Gbps per lane. Within the module, the optical multiplexing and demultiplexing of these four wavelengths are efficiently managed.

Let’s explore its capabilities:

1. Lightning-Fast Speed
