Cisco CPAK^® 100GBASE fiber modules for Cisco^® switches and routers offer a selection of high-density 100-Gbps connectivity solutions. The modules are especially well suited for connections in enterprise and service provider data centers and in service provider edge networks.

The line cards use the Cisco CPAK form factor. They are 20 percent smaller and consume 40 percent less power than C Form-Factor Pluggable 2 (CFP2) modules; they use 70 percent less power than the CFP interface. Cisco CPAK modules give you up to 20 percent greater port density and front-panel bandwidth than competing products.

Choose the model that matches the distance you need to cover, the type of fiber cabling you are using, and the Cisco networking product you are using. Cisco CPAK 100GBASE modules work in the following Cisco networking equipment: ASR 9000 Series Router; CRS-X Carrier Routing System; NCS 2000, 4000, and 6000 Series Routers; the Nexus 7000 and 7700 Series Switches, and the Cisco ONS Transport Platform.

Features and benefits

Cisco CPAK modules combine the greatest density and bandwidth with the lowest power consumption available in the market. They are interoperable with any IEEE-compliant 100GBASE-LR4 or 100GBASE-SR10 for investment protection and product choice. Some models, including the Cisco CPAK 100GBASE-LR4, use Cisco Complementary Metal-Oxide Semiconductor (CMOS) photonic technology to provide industry-leading optical integration, performance, power savings, and scalability.

The key features of Cisco CPAK 100GBASE modules are listed in Table 1.

Cisco CPAK 100GBASE-LR4 Module

The primary application of the Cisco CPAK-100G-LR4 and CPAK-100GE-LR4 modules is to support 100Gbps optical links over standard Single-Mode Fiber (SMF, G.652) terminated with SC connectors (Figure 1) or LC connectors (Figure 2).

The LR4 module is IEEE 802.3ba-compliant and supports link lengths of up to 10 km over standard SMF, G.652. It delivers an aggregate data signal of 100 Gbps, carried over four LAN Wavelength-Division Multiplexing (WDM) wavelengths operating at a nominal 25 Gbps per lane. Optical multiplexing and demultiplexing of the four wavelengths are managed within the module.

The primary application of the Cisco CPAK-100G-ER4L module is to support 100-Gbps optical links over standard single-mode fiber (SMF, G.652) terminated with SC connectors. Nominal power consumption is less than 7.5W.

The ER4 Lite module is compatible with the 100GBASE-ER4 standard and supports link lengths up to about 25 km over standard SMF, G.652. It delivers an aggregate data signal of 100 Gbps, carried over four LAN Wavelength-Division Multiplexing (WDM) wavelengths operating at a nominal 25 Gbps per lane. The module can be used over longer distances in engineered links with CPAK-100G-ER4L modules at both ends. Optical multiplexing and demultiplexing of the four wavelengths are managed within the module.
