QSFP28 O-Band DWDM 100G Ethernet SM 25km 15dB LC
A QSFP28 form-factor O-Band DWDM transceiver for 100Gbps Ethernet applications.
Product information
TQ2026-OxxC-SO is a QSFP28 form-factor O-Band DWDM transceiver for 100 Gbps Ethernet applications. It is intended for use in intra- and interconnect applications within and between data centers between switches, routers, storage equipment etc.
The transceiver is provided in 16 channel versions with 200GHz spacing. The optical performance enables distances of up to 25km over a SingleMode (SM) G.652 fiber-pair cable. The wavelengths are located in the O-band (1300nm region) where the dispersion is at a minimum, enabling un-amplified solutions with a distance not achievable in the normal DWDM band, unless using amplifiers and dispersion compensation.
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 TQ2026-OxxC-SO transceivers uses a single lane carrier @ 50Gbaud with 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.
The transceivers provide digital diagnostic functions via a 2-wire serial interface as defined by the SFF-8472 specification.
