QSFP28 BiDi 100G 70km
A 70km QSFP28 form-factor BiDi transceiver for 100Gbps Ethernet applications
Product information
The TQ2034-BXXy-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 each inject four LAN-WDM wavelengths into the same single-fiber. The solution thus consists of two transceivers; TQ2034-BWXC-SO transmitting at the lower wavelengths 1274/1278/1282/1287nm and TQ2034-BXWy-SO transmitting at the high wavelengths 1296/1300/1305/1309nm. 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.
TQ2034-BXXy-SO has an optical performance enabling distances of up to 70km over a SingleMode (SM) G.652 fiber-pair cable. Forward Error Correction (FEC) is required to be implemented by the host in order to ensure reliable system operation. The FEC type shall be as defined in IEEE802.3bj, i.e. Reed Solomon RS(528,514). The optical parameters will provide a bit error ratio (BER) of 5 x 10-5. FEC will render in the required BER of better than 1 x 10-12.
Digital diagnostics functions (DDM) are available via an I2C interface, as specified by the QSFP28 MSA. The transceiver is available in two temperature range options, one being the Extended temperature range (E-temp): -20°C to 85°C (-20°F to 185°F).
