PacketLight’s PL-8000M muxponder
PacketLight Networks, has launched the PL-8000M 2 x 800G Muxponder, designed to address the growing demand for high- capacity, cost-effective optical transport solutions. The company says the technology and flexible architecture make the PL-8000M ideal for rolling out 800GbE, 400GbE, and 100GbE services or for enhancing existing network capacity. The device delivers up to 1.6Tbps of capacity using two 800G pluggable OpenROADM coherent optical modules in a 1U device. The device integrates mux/demux, EDFAs, and an optical switch, offering a complete optical networking solution that simplifies deployment and reduces operational costs. Designed with a pay-as-you- grow architecture, the PL-8000M
ensures future-proof scalability. Its interoperability with any third- party switch or router allows seamless integration into existing networks while providing a full demarcation point between the service and the DWDM network. This enables complete visibility and performance monitoring for client services. It also supports
400GbE and 800GbE services, and supports Layer-1 GCM- AES-256 encryption for secure communications, as well as QKD for future encryption needs. The device ensures efficient utilization of the optical spectrum and high-performance transport reducing the number of coherent transceivers needed. It is aimed at high-capacity data centre interconnect
(DCI) for enterprise, AI, and cloud computing networks; service provider managed optical transport demarcation; upgrading existing OTN/ DWDM infrastructure with 800G wavelengths; and secured and encrypted communication for 100/400/800GbE services. PacketLight will demo the device at the 2025 OFC exhibition, booth 3232.

Yokogawa T&M’s AQ6377E optical spectrum analyser
Yokogawa Test & Measurement Corporation has released the AQ6377E optical spectrum analyser for mid-wave infrared (MWIR) measurements. The AQ6377E offers a number of new features and functions over the previous AQ6377 model that enhance speed, accuracy, and capability, enabling it to meet a broader spread of laser application demands, including environmental measurement. As the successor model to the AQ6377, the AQ6377E optical spectrum analyser presents users with a number of new functions and specifications. For instance, the AQ6377E offers improved performance of the built-in chopper, a device that modulates light by periodically interrupting light rays with a vane that rotates
Yokogawa says the AQ6377E also offers much wider pulsed light measurement capabilities thanks to the addition of a new function, ‘advanced pulsed light measurement mode’. This enhancement provides engineers with improved ability to measure pulsed light with low-repetition frequencies that were previously impossible to achieve using the AQ6377. In laser evaluation, simultaneous measurement over a wide level range was a clear performance advantage of the previous AQ6377. The new AQ6377E adds to this with a dynamic measurement range for the simultaneous measurement of a laser’s optical spectrum. This improvement ensures engineers can accurately evaluate the SMSR, an index of laser performance, which is difficult to achieve with an FT-OSA.
at a constant speed, which operates automatically according to the measurement sensitivity setting. Specifically, Yokogawa has added the NORMAL/CHOP and MID/CHOP measurement sensitivity settings, which apply the lock-in detection function to
the intermediate NORMAL and MID sensitivities of the previous model. This capability reduces the impact of background noise when measuring MWIR light spectra and allows faster and more accurate measurement compared with the previous AQ6377.
