QSFP28 BiDi 50G Ethernet 1294.40nm/1308.24nm SM 40km 18dB LC

The SO-QSFP28-50GE-BX40D-2930/3029 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; SO-QSFP28-50GE-BX40D-2930 and SO-QSFP28-50GE-BX40D-3029, operating at transmit wavelengths 1294.40nm and 1308.24nm 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.

The transceivers have a 2x26.5625Gbps electrical interface which are transformed into a single PAM4 modulated, single wavelength solution at 52.125Gbps. The transceiver pair supports 50GbE services, having an optical performance that provides a bridgeable distance of up to 40km.

As stipulated by the 50G Ethernet standards, Forward Error Correction (FEC) is required to be implemented by the host equipment in order to ensure reliable system operation. The optical parameters below will provide a bit error ratio (BER) of 2.4 x 10^-5 for 50G Ethernet. FEC will provide the required quality for secure service.

The transceivers provide digital diagnostic functions via a 2-wire serial interface as defined by the SFF-8472 specification.

Two products: SO-QSFP28-50GE-BX40D-2930 (Tx/Rx=1294.40nm/1308.24nm) and SO-QSFP28-50GE-BX40D-3029 (Tx/Rx=1308.24nm/1294.40nm).
