Cisco CPAK-10X10G-LR 100GBASE-LR 10x10G Long-Reach CPAK Transceiver Module （1310nm 10km MPO-24 SMF DOM） The Cisco CPAK-10X10G-LR module is a high-performance 100-Gigabit optical transceiver designed for long-reach data transmission over 24-fiber Single-Mode Ribbon Cables (SMF). Operating at a nominal wavelength of 1310nm, this module supports links up to 10 kilometers. It features a 24-fiber MPO/MTP APC (Female) connector and is highly optimized for 10x10G breakout applications, allowing seamless and high-density aggregation between 100G core switches and ten legacy 10GBASE-LR optical interfaces.

Product Highlights
1.Special Parallel Single-Mode Design
- Unlike common 100G-LR4 wavelength division multiplexing (WDM) modules that utilize an LC interface, this model features a native Parallel Single-Mode (PSM) optical design. Each 10G lane transmits independently over a dedicated fiber core, eliminating optical crosstalk and ensuring pristine transmission quality.
2.MPO-24 Matches Full-Duplex Channel Demand
- The 24-fiber MPO/MTP APC interface perfectly accommodates the 20-core full-duplex transmission requirements of the $10 \times 10\text{Gbps}$ architecture (10 TX + 10 RX lanes). This native high-density interface eliminates the core-count limitations found in legacy LC and MPO-12 connectors.
3.Reliable 10km Long-Distance Transport
- With an optimized single-mode optical path design, this module delivers stable and robust 100G signal transmission across distances up to 10 kilometers (over G.652 SMF), providing an exceptional balance between massive bandwidth and extended reach.
4.Seamless Compatibility with Cisco Platforms
- Engineered and factory-calibrated by Cisco, this original module guarantees seamless plug-and-play operation on Cisco switches and routers, significantly reducing deployment risks and simplifying late-stage network maintenance.
5.Highly Flexible 10x10G Breakout Architecture
- Optimized for high-density 10x10G-LR breakout modes. When paired with an MPO-24 APC to 10x Duplex LC single-mode breakout cable, it allows core 100G hardware to aggregate ten discrete, long-reach 10G networks effortlessly.
6.Compact CPAK Energy Efficiency
- The specialized compact CPAK form factor consumes up to 45% less power than traditional CFP2 modules (maximum power consumption $< 5.0\text{W}$), greatly reducing the thermal load and operational expenses (OPEX) of green data centers.
