The TQ2020-BxxC-SO is a bi-directional transceiver solution operating directly on a single-fiber without the need for a separate optical filter. This is achieved by having two transceivers that inject different wavelengths into the same single-fiber. The solution thus consists of two transceivers; TQ2020-BADC-SO and TQ2020-BDAC-SO, operating at transmit wavelengths 1271nm and 1331nm respectively. Using a single-fiber solution provides a cost-efficient solution for interconnect and it simplifies the patching since no separate transmit/receive direction has to be taken into account.
TQ2020-BxxC-SO has an optical performance enabling distances of up to 10km over a SingleMode (SM) G.652 fiber-pair cable. The module includes FEC coding Forward Error Correction (KP4 FEC) to ensure reliable system operation. The host system shall thus not have FEC activated. The optical parameters will provide a bit error ratio (BER) of 2.4 x 10-4. FEC will render in the required BER of better than 1 x 10-12.
The TQ2020-BxxC-SO transceivers uses a single 1271nm or 1331nm channel/lane @ 50Gbaud using PAM4 modulation to transport the Ethernet signal. The electrical interface is 4x 25.78Gbps and compliant with OIF CEI-28G-VSR. Digital diagnostics functions (DDM) are available via an I2C interface, as specified by the QSFP28 MSA.
