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.
