PacketLight Networks Announces Advanced Features in the PL-4000M Muxponder/ADM

Tel Aviv, July 17, 2023PacketLight Networks, a leading provider of DWDM and OTN equipment, has upgraded the PL-4000M muxponder to support the transport of 600 Gb/s in the current 1U device. This enables providers to increase network backbone capacity cost-effectively and speed the introduction of new services.

The PL-4000M aggregates a mix of Ethernet, Fibre Channel, and OTN services into uplinks of 200/300/400Gb/s capacity. In addition, the device now also supports 25 GbE service type, leveraging existing 10 GbE fiber optic cables.

It delivers cost-effective, high-capacity transport of 10/25/100 GbE, 16G FC, and OTU2/2e/4 services over 200/300/400 Gb/s wavelengths with enhanced spectral efficiency. The device expedites the implementation of new services and increases the capacity of existing DCI, metro, short-haul, and long-haul network backbones. It achieves this by utilizing alien wavelengths without requiring the replacement of existing infrastructure.

The PL-4000M supports 25 GbE client service over existing 10 GbE cables, using fewer optical modules to deliver double the density, and saving and simplifying network upgrades. The integrated 1U footprint saves rack space, and low power consumption per transmitted bit, all of which reduce the overall cost of the transport solution. It offers high levels of security with embedded Layer-1 GCM-AES-256 optical encryption using elliptic curve Diffie-Hellman key exchange, FIPS-140-3 level 2 compliant.

“This latest upgrade to the PL-4000M represents a leap forward in performance and functionality, and that benefits both current and future deployments, and 5G front-haul applications,” said Koby Reshef, CEO of PacketLight. “With this upgrade, we continue our commitment to delivering cutting-edge technology that exceeds our customers’ expectations and sets new standards in the industry.”

The PL-4000M supports 200/300/400 Gb/s uplinks over CFP2-DCO Open ROADM coherent pluggable modules, eliminating vendor lock-in, reducing long-term total cost of ownership (TCO), and accelerating return on investment (ROI). Flexible configuration of the uplinks enables transport of up to 600Gb/s, with each uplink transporting 200Gb/s QPSK in ultra-long haul applications, 300 Gb/s QAM16 in metro and long haul applications, or 400G 16QAM in DCI and metro applications.

The PL-4000M provides full demarcation between the service and the OTN/DWDM uplink and offers seamless interoperability with third-party switches and routers. The product delivers full visibility and performance monitoring of both the line optical transport layer (OTN) and service interfaces.
