PacketLight Networks debuts PL 4000G transponder for 4.8T in 1RU

Dec. 16, 2021
The system will accommodate a flexible mix of 400 Gigabit Ethernet (GbE) and 100GbE client traffic over 400-Gbps wavelengths via pluggable coherent modules.

PacketLight Networks has unveiled the PL-4000G transponder, designed to provide 4.8 Tbps of capacity in 1RU for data center interconnect applications. The system will accommodate a flexible mix of 400 Gigabit Ethernet (GbE) and 100GbE client traffic over 400-Gbps wavelengths via pluggable coherent modules.

The PL-4000G supports up to 12x400GbE or up to 48x100GbE client services via QSFP-DD SR8/LR8 or QSFP-DD DR4/FR8 pluggable modules, respectively. On the line side, the transponder can use 400ZR or OpenZR+ coherent pluggables with industry-standard CFEC and OFEC, respectively. The transponder integrates mux/demux, two EDFAs, and an optical switch to deliver a complete DWDM/OTN end-to-end platform in a 1RU form factor. The PL-4000G can serve as a full demarcation point between the 100GbE and 400GbE client services and the DWDM and is interoperable with any third-party vendors’ switches and routers, PacketLight asserts.

“We are happy to introduce this optical transport device to the market, answering our customers’ needs for a high-capacity integrated platform in a compact footprint, saving network operational expenses, and reducing power and cost per bit,” said Koby Reshef, CEO of PacketLight Networks. "Our vendor-agnostic solution enables smooth and cost-effective migration to 400G networks with optimal cost and performance, while supporting 400ZR and OpenZR+ industry standards.”
