Coherent Corp. (NYSE:COHR), the global leader in photonics, today announced the expansion of its Pluggable Optical Line System (POLS) portfolio, with the full C-band, high-power variable-gain amplifier optical line system in a compact QSFP form factor. Designed for the latest generation of 800G ZR/ZR+ digital coherent optics, the enhanced POLS supports up to 32 DWDM wavelengths over a single fiber pair, enabling as much as 25.6Tbps of AI datacenter traffic across links from 2km to 200km.

Targeting the high-capacity interconnect requirements of Internet Service and Cloud Hosting Providers, and AI infrastructure operators, the enhanced POLS integrates key optical transport functions into QSFP modules that plug directly into standard transceiver slots. Thanks to Coherent’s high-performance miniature optical components, including dual-chip micropump lasers, POLS provides 21dBm output power, variable gain, low power consumption, and autonomous plug-and-play operation. Auto-provisioning manages link configuration and laser safety, while fixed wavelength and colorless MUX/DMUX options and asymmetric optical connectors simplify deployment and help prevent fiber-connection errors.
