ATGBICS by Approved Technology Ltd AFBR-79EIDZ-OR2-C

AFBR-79EIDZ-OR2-C is a parallel 40Gbps Quad Small Form-factor Pluggable (QSFP) optical transceiver module designed to increase port density and reduce total system cost. This QSFP full-duplex optical module provides 4 independent transmit and receive channels, each capable of operating at 10Gbps, delivering a total bandwidth of 40Gbps over OM3 MMF with a reach of up to 70m, and up to 150m over OM4 MMF.

Fiber ribbon cables with MPO/MTP connectors on both ends are inserted into the QSFP module receptacle. The ribbon cable orientation is "keyed," and guide pins inside the module receptacle ensure proper alignment. Cables are typically non-twisted (key-up to key-up) to ensure correct inter-channel alignment. Electrical connection is achieved via a z-style pluggable 38-pin IPASS connector.

The module is powered by a single +3.3V supply and provides LVCMOS/LVTTL global control signals including module present, reset, interrupt, and low-power mode. A two-wire serial interface is provided for transmitting and receiving more complex control signals and accessing digital diagnostic information. Individual channels can be addressed, and unused channels can be disabled for maximum design flexibility.

The AFBR-79EIDZ-OR2-C is designed in accordance with the QSFP Multi-Source Agreement (MSA) for form factor, optical/electrical interface, and digital diagnostics interface. It is intended to withstand the most severe external operating conditions, including temperature, humidity, and EMI. The module features a very high level of functionality and feature integration, accessible via the two-wire serial interface.
