The FIT Optical Interconnect Technology AFCT-91DRDDZ is an Eight-Channel, Pluggable, Multi-mode, Fiber-Optic QSFP-DD transceiver for 400 Gigabit Ethernet Applications. This high performance transceiver module is intended for short-range data communication and interconnect applications. It converts eight host electrical data lanes in each direction into eight optical lanes at 50Gbps giving an aggregated bandwidth of 400Gbps, using two laser colors per fiber in a MMF BiDi configuration. It allows optical communication up to 100m over an 4+4 optical fiber MPO connectored multi-mode OM4 cable. The pull tab facilitates insertion and extraction of these transceivers in high density configurations. Each electrical lane operates at 26.5626 GBd / 53.125 Gbps (PAM4 encoded) and conforms to the IEEE 400GAUI-8 interface with host KP FEC.

These modules are designed to operate over multimode fiber systems using nominal wavelengths of 850nm and 910nm. The electrical interface uses a 76 contact QSFP-DD edge type connector. The optical interface uses a conventional 4+4 MPO MMF connector. This module incorporates FIT Optical Interconnect Technology proven integrated circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
