Product Overview
The 800G OSFP DR8 (Octal Small Form Factor Pluggable Dual – Range 8 – channel) is a high – performance optical communication module designed for the requirements of next – generation data centers and high – speed networks. Based on the OSFP packaging standard, this module supports 8 – channel parallel transmission, with a single – channel rate of 100Gbps and a total rate reaching 800Gbps. It is specifically optimized for high – bandwidth scenarios such as ultra – large – scale data centers, cloud computing core networks, AI/ML clusters, and 5G backbone networks. Its DR8 specification indicates that it supports transmission over single – mode fiber (SMF) with a maximum transmission distance of up to 500 meters, meeting the needs of data center inter – connectivity (DCI) and short – range metropolitan area networks.

Technical Notes
- Note 1: Average launch power, each lane (min) is informative and not the principal indicator of signal strength
- Note 2: Transmitter reflectance is defined looking into the transmitter.
- Note 1: Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with a value of SECQ up to 3.4 dB.
- Note 2: Measured with conformance test signal at TP3 for the BER = 2.4×10−4
