Eoptolink: 800G DR8 OSFP Transceiver with Multi-core Fiber Interface

Eoptolink’s 800G DR8 OSFP transceiver with multi-core fiber interface offers higher capacity, efficiency, and scalability than single-core fiber (SCF).

Eoptolink’s 800G DR8 OSFP transceiver with multi-core fiber interface provides 8 electrical host-interface lanes and 8 optical lanes, each operating at 106.25 Gbps (53 Gbaud with PAM4). Compliant with the IEEE 802.3 standard for 800GE-DR8 and the OSFP MSA Specifications, the optical interface of the 800G DR8 transceiver features dual MPO-12 connectors with 4 strands of multi-core fiber (MCF). This module supports transmission distances up to 500m with a single-mode MCF cable. Instead of laying multiple single-core fibers, MCF consolidates them into a single strand, reducing cable bulk, installation space, and weight, which is crucial in dense environments such as large data centers. 

Judge’s comment: “By using 4-core MMF in their multicore 800G DR8 OSFP transceiver, Eoptolink moves the needle in both moving new advanced fiber designs into practical high-volume applications.”
