By multiplexing four distinct shortwave wavelengths (850-940nm) over the same fiber pair, it provides a cost-effective solution for upgrading existing multimode fiber infrastructure to 100G without requiring cabling changes. This transceiver is ideal for high-density data center interconnects, offering simplified fiber management and backward compatibility with OM3/OM4 multimode cabling systems.

A high-speed optical module that enables 100G Ethernet transmission over a single strand of multimode fiber using Bidirectional (BiDi) technology and standard LC connectors. By employing two different wavelengths (e.g., 850nm/900nm) on the same fiber strand, it achieves 100Gbps full-duplex communication over distances up to 100 meters on OM4 fiber. 

A single-lane, hot-pluggable optical module designed for 100G Ethernet  applications over single-mode fiber with LC connectors . Operating at a wavelength of 1310nm, it supports transmission distances of up to  500 meters using PAM4 modulation technology. This transceiver complies with the 100GBASE-DR1 standard (IEEE 802.3cd) and is ideal for cost-effective, high-density data center interconnects, leaf-spine architectures, and other short-reach single-mode fiber applications where simplified fiber infrastructure and power efficiency are critical.

A single-wavelength, hot-pluggable optical module designed for 100G Ethernet applications over single-mode fiber with standard LC connectors. Operating at 1311nm wavelength, it supports transmission distances of up to 2 kilometers in compliance with the 100GBASE-FR1 standard (IEEE 802.3cu). This transceiver is particularly suitable for data center interconnects, enterprise networking, and telecommunications access networks, offering a balance of performance and power efficiency while maintaining compatibility with existing LC fiber infrastructure.
