QSFP28 100GE-FR CWDM 2km 4dB LC

The SO-QSFP28-100G-FRx is a QSFP28 form-factor transceiver for 100Gbps Ethernet applications. It is intended for use in intra- and interconnect applications within and between data centers between switches, routers, storage equipment etc.

SO-QSFP28-100G-FRx is a single-lambda 100G transceiver provided in four different CWDM wavelength versions that match the wavelengths of the 400G Transceiver SO-QSFP-DD-4C-LR4 to support a 400G to 4x 100G break-out configuration.

SO-QSFP28-100G-FRx 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.

SO-QSFP28-100G-FRx uses a single CWDM 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.

Four products: SO-QSFP28-100G-FRA (1271nm), SO-QSFP28-100G-FRB (1291nm), SO-QSFP28-100G-FRC (1311nm) and SO-QSFP28-100G-FRD (1331nm).
