Source Photonics offers 100G ZR4 QSFP28 optical transceiver
Source Photonics used this week’s ECOC 2020 virtual event to announce a 100G ZR4 QSFP28 optical transceiver for 80-km single-mode fiber applications such as data center interconnect and router interconnect. The module is based on 4x25G NRZ optics.
The company points out that the use of NRZ offers lower cost and power consumption than coherent-based alternatives, while the QSFP28 form factor offers space savings over legacy CFP and CFP2 interfaces. The optical transceiver is fully compliant with the QSFP28 specifications and related MSA described in the latest SFF-8665/8636. It also complies with IEEE 802.3 100GBASE-ZR4 related specifications.
The QSFP28 ZR4 offers digital diagnostic functions through an I2C interface. The module also supports standard KR4 forward error correction (FEC) baud rates which will help receive-side detect, correct bit errors, and improve the overall quality of the link. The up to 80-km point-to-point reach is attainable without optical amplification and dispersion compensation.
Source Photonics says the 100G ZR4 QSFP28 optical transceiver is currently sampling.
