Manufacturer ONT Optical Network Terminal OSFP

C-LIGHT, TE Connectivity, LINK-PP, NADDOD, and Molex are key manufacturers providing OSFP-based optical transceivers and connectors for high-speed networking applications.

Overview of OSF

P TechnologyOSFP (Octal Small Form Factor Pluggable) is an open standard optical transceiver interface designed for ultra-high-speed Ethernet and data center interconnects. It supports eight electrical lanes per module, each capable of up to 100G PAM4 signaling, enabling total bandwidths of 400G, 800G, and up to 1. 6Tbps depending on configuration.

OSF

P modules are slightly larger than QSFP-DD modules to accommodate higher power dissipation (15–20W) and improved thermal management, making them ideal for AI clusters, hyperscale data centers, and high-performance computing environments. Key Manufacturers and ProductsC-LIGHT: Offers a range of OSFP optical transceivers, including 1. 6T OSFP-RHS, 800G OSFP, and 400G OSFP modules.

Their products support multiple transmission distances (50m to 2km) and comply with IEEE 802. 3 standards, CMIS Rev5. 2, and QSFP112 MSA hardware protocols.

C-LIGHT also provides complementary optical components like patch cords, attenuators, and optical distribution frames.

T

E Connectivity: Provides OSFP connectors and cable assemblies supporting aggregate data rates from 200G to 1. 6T, with integrated thermal heatsinks to manage heat at high data rates. TE's OSFP solutions are compatible with 28G NRZ, 56G PAM4, 112G PAM4, and 224G PAM4 signaling, offering flexibility for evolving data center architectures.

LINK-PP: Focuses on OSFP transceivers for 400G and 800G Ethernet, emphasizing thermal optimization, high-density connectivity, and interoperability across vendors via the OSFP MSA framework.

NADDO

D: Offers 400G OSFP Ethernet transceivers with robust thermal solutions (OSFP IHS and RHS), supporting multimode fiber connections up to 100 meters and high-speed interconnects between switches and NICs. Molex: Supplies OSFP connector systems supporting up to 224Gbps per lane and aggregate rates of 1. 6Tbps, with options for DACs, active cables, and pluggable transceivers.
