• CPAK 100GBASE-LR4
Supports 100-Gbps optical links over standard single-mode fiber (SMF, G.652) terminated with SC
connectors. Nominal power consumption is less than 5.5W.
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 wavelength-division
multiplexing (WDM) wavelengths operating at a nominal 25 Gbps per lane in LAN mode. OTU4 rate
is also supported. Optical multiplexing and demultiplexing of the four wavelengths are managed within
the module.

• CPAK 10x10G-LR
Used in 10 x 10-Gbps mode along with ribbon-to-duplex SMF breakout cables for connectivity to ten
10GBASE-LR optical interfaces. It supports link lengths up to 10km over standard SMF, G.652. The
module delivers 10Gbps industry-standard links, and optionally 40 Gbps links for CPAK-to-CPAK
applications.
• CPAK 100GBASE-PSM4
The Cisco CPAK-100G-PSM4 Module supports link lengths of up to 500 meters over Single-Mode Fiber
(SMF) with MPO connectors. The 100 Gigabit Ethernet signal is carried over 12-fiber parallel fiber
terminated with MPO multifiber connectors. This module supports 100G LAN mode only; OTN modes
and breakout are not supported.
• CPAK adapter module
The CPAK adapter module is a hot-swappable pluggable adapter module that serves as a physical host
for a 40GE QSFP+ transceiver module and enables a 40GE QSFP+ transceiver module to be connected
to a CPAK port. From the QSFP+ transceiver module perspective, the CPAK adapter module is the host
device. From the CPAK port perspective, the adapter module is a CPAK transceiver module. The CPAK
adapter module is powered only if it has a QSFP+ transceiver plugged in. Hence, the router detects the
CPAK adapter only when the adapter holds a QSFP transceiver module.
