Technologies and Products

Source Photonics, has released its new 100G ZR4 QSFP28 transceiver for 80km high-speed data centre interconnects and routing applications. Leveraging the widely deployed 4 x 25G NRZ optics, 100G ZR4 QSFP28 is the latest addition to the company’s 100G product lines among its 100/200/400G portfolio of single-mode transceivers for datacentre and routing applications.

Source Photonics says cloud traffic continues to drive data centre growth and the industry requires cost-effective and high-bandwidth interoperable solutions. The Source Photonics 100G ZR4 QSFP28 is a cost optimised and low-power transceiver supporting 100G Ethernet for extended reach up to 80km transmission that provides point to point network connectivity solutions between data centres or central offices without the need to deploy either complicated, power hungry, and expensive coherent solution or legacy CFP/CFP2 interfaces. The 100G ZR4 QSFP28 alleviates the fibre shortage bottlenecks and enables hyperscale cloud operators to scale their network.

The transceiver is in QSFP28 form factor, the smallest for 100G 80km solution. It is fully compliant with the industry standard QSFP28 and related MSA described in the latest SFF-8665/8636 and digital diagnostic functions are available through an I2C interface. It also complies with IEEE 802.3 100GBASE-ZR4 related specifications. In addition, the module supports standard KR4 FEC (Forward Error Correction) baud rates which will help receive side detect and correct bit errors and improve the overall quality of the link. The 100G ZR4 QSFP28 transceiver is capable to operate over up to 80km point-to-point link without the need for optical amplification and dispersion compensation.
