The CPAK-100GE-LR4 is a Cisco-compatible CPAK form-factor 100GBASE-LR4 optical transceiver designed for single-mode fiber links up to 10 km without OTN support.
This module supports reliable 100 Gbps data transmission over single-mode fiber distances up to 10 kilometers.
The CPAK-100GE-LR4 requires ITU-G.652 single-mode fiber (SMF) to achieve the full 10 km reach at 100 Gbps.
It uses four coarse WDM lanes centered around 1310 nm, each carrying 25 Gbps, to deliver the aggregate 100 Gbps signal.
Yes, it is fully compatible with Cisco switches and routers offering CPAK 100G interfaces and meets the MSA specifications.
Yes, it is MSA-compliant and interoperable with any network device that accepts CPAK 100GBASE-LR4 optics.
No, this module provides a raw 100GBASE-LR4 signal and does not include OTN encapsulation or mapping.
Installation is plug-and-play: insert the module into a CPAK port until the latch clicks and connect the single-mode fiber patch cables.
The CPAK-100GE-LR4 consumes up to 11 watts under full-load conditions, ensuring efficient thermal management.
Yes, it features DDM/DOM capabilities for real-time monitoring of optical power, temperature, voltage, and laser bias current.
It is RoHS-compliant, MSA-certified, and adheres to IEEE 802.3bm 100GBASE-LR4 standards, plus CE and FCC regulations.
The module operates reliably between 0 °C and +70 °C (32 °F to 158 °F) for standard commercial environments.
It is ideal for high-capacity data center uplinks, enterprise core networks, metro aggregation, and service provider backbone links.
Always keep dust caps on unused ports, use fiber-optic cleaning tools for connectors, and avoid bending fibers beyond the specified radius.
The CPAK-100GE-LR4 includes a one-year limited warranty with full technical support and access to firmware updates.
Use low-loss single-mode fiber, verify end-to-end link budget, monitor DDM parameters, and adhere to proper installation practices.
