1.6T Muxponder / Transponder

The PL-4000T is a modular and cost-effective high capacity solution for rolling out 400GbE and 100GbE services, or increasing existing network capacity. The device supports up to four 400G DCO pluggable uplink optical modules, delivering up to 1.6T in a 1U chassis.

The PL-4000T can be optionally integrated with EDFA, mux/demux, and an optical switch for fibre protection, delivering the entire DWDM/OTN end-to-end infrastructure solution in a 1U form factor. Furthermore, Layer-1 AES256 encryption can be provisioned on a per port basis.

Integrated Optical Protection

In 1+1 facility protection (fiber path protection) the emphasis is on protecting the fiber link and is enabled by an optical switch embedded in the muxponder/transponder, or in the amplification chassis (when amplification is required), as shown in Figure 1.
The optical switch enables fiber path protection by switching between the working and protecting paths in less than 50 milliseconds.

In order to provide secured fiber optic link, a combination of protection methods must be in place: physical on-site protection, secured management protocols, encryption, and monitoring. This combination provides network administrators with the tools they need to prevent, detect, isolate and counter any potential or occurring data hacking attempt.

Layer 1 GCM-AES-256 Encryption

Supports independent vendor-agnostic bi-directional encryption/decryption machines, where each port can be configured to a different service rate/type, and has its own key exchange and pre-shared secret. Each service is isolated and encrypted independently of the others. The user can flexibly activate the
encryption/decryption functionality for specific transponders and wavelengths.

The product is FIPS 140-2 Level 2 and Common Criteria EAL2 compliant, and provides GCM-AES-256 bit encryption and key exchange based on the Diffie-Hellman (DH) protocol, without compromising performance.

Upgrading to 400G capacity per wavelength requires consideration of the unique challenges associated with 400G technology. For example, 40G, 100G and 200G capacities do not require special infrastructure changes, as their wavelength spectral bandwidth is the same. 400G capacity over a single wavelength has a high baud rate, which is spectrally too wide to pass through 50GHz channel-spaced filters and fixed 50GHz grid ROADMs (reconfigurable optical add-drop multiplexers). A new “runway” is required to accommodate these higher rates.

Prior to 400G, optical fibre original equipment manufacturers (OEMs) created products that reduced rack space and optimised power to keep OPEX and CAPEX low. The introduction of the next generation transponders and muxponders based on pluggable 400G optics, ensures that future upgrades to 400G capacity will maintain the flexibility, modularity, and power-saving capabilities many network operators and enterprises are accustomed to.
