Comparison
Generic vs Vendor-Specific Optical Module
By C-LIGHT Marketing丨Oct 12, 2026
Generic and vendor-specific optical modules offer different approaches to network compatibility, purchasing flexibility, and technical support.
QSFP-DD vs OSFP Port Density
By C-LIGHT Marketing丨Oct 11, 2026
QSFP-DD and OSFP enable high-density 400G and 800G connectivity, but differ in module dimensions, cooling design, and backward compatibility.
OSFP vs OSFP-RHS Port Density
By C-LIGHT Marketing丨Oct 10, 2026
OSFP and OSFP-RHS differ in mechanical height, thermal integration, and front-panel layout.
Scale-Up vs Scale-Out vs Scale-Across Networks
By C-LIGHT Marketing丨Oct 9, 2026
Scale-up, scale-out, and scale-across are the three interconnection layers of AI infrastructure. Compare their bandwidth, latency, protocols, reach, and economics—from NVLink within a rack to Ethernet and InfiniBand fabrics, and to optical links between AI data centers.
DWDM vs Coherent Optics
By C-LIGHT Marketing丨Oct 8, 2026
DWDM and coherent optics address different aspects of optical transmission, with differences in wavelength multiplexing, modulation, detection, reach, spectral efficiency, DSP, power, and network applications.
ROADM vs OADM
By C-LIGHT Marketing丨Oct 7, 2026
ROADM and OADM provide wavelength add and drop functions in WDM networks, with major differences in reconfigurability, wavelength routing, network direction, automation, scalability, and applications.
SN vs CS
By C-LIGHT Marketing丨Oct 6, 2026
SN and CS are compact duplex fiber connectors for high-density optical networks, with differences in connector design, packing density, polarity, breakout architecture, Base-2 and Base-8 connectivity, and data center applications.
MDC vs CS
By C-LIGHT Marketing丨Oct 5, 2026
MDC and CS are high-density duplex fiber connectors with different mechanical designs, connector density, polarity options, breakout architectures, and data center applications for 400G, 800G, and higher-speed networks.
CPO vs On-Board Optics
By C-LIGHT Marketing丨Oct 4, 2026
CPO and on-board optics move optical engines closer to the switch ASIC to improve high-speed interconnect efficiency. Compare their integration level, electrical distance, power, thermal design, bandwidth density, serviceability, manufacturing complexity, and AI data center applications.
AI Optical Transceiver vs Traditional Data Center Transceiver
By C-LIGHT Marketing丨Oct 3, 2026
AI optical transceivers are optimized for the high bandwidth, density, power, and reliability demands of GPU clusters. Compare them with traditional data center transceivers across speed, signaling, reach, power, latency, protocols, thermal design, and deployment.
