Lessengers intros partially retimed 800G Optical Transceivers

LESSENGERS is unveiling a portfolio of 800G optical transceivers based on its patented “direct optical wiring” (DOW) technology.

Lessengers is adding partially retimed capability to its 800G transceiver product portfolio, which in one product entails an integrated DSP chip on the transmitter side. This capability will enable a wide range of interoperability with other pluggable transceivers and lower power consumption due to the use of a half retimer. 

Messengers AI/ML product now features the following integrated retimer electronics along with existing fully retimed optics:

* Linear drive - linear pluggable optics (LPO)

* Linear receive - half-retimed linear optics (HALO) or linear receive optics (LRO)

800G Linear Receive Optical Transceiver now offers:

* Lower power consumption – less than 9 W for an 800G (2 × SR4) OSFP

* IEEE 802.3 and CMIS 5.0 or later compliant

* 8 × 112 Gb/s PAM4 on both the electrical host receiver and optical line transmitter interfaces

* A half retimer chip integrated in the transmit path from the electrical input to the optical line side output for enhanced signal retiming and equalization.

Lessengers' DOW is a polymer-based air-cladded waveguide technology that is particularly useful for optical interconnects in the data center and high-performance computing environments.
