Of the five common types of 100G transceiver modules found within the data center, two types - CWDM4 and PSM4 are targeted at data communications up to 2km. SR4 (500m), LR4 (10km) and ER4 (40km) are the other types typically specified for 100G data communications. POET’s focus on CWDM4 and LR4 designs is based on its unique and differentiating capability to integrate a fully monolithic 4-channel multiplexing and demultiplexing functionality directly into its waveguides, avoiding the costly requirement to align and couple additional devices into a transceiver module. POET’s LR4 design converts 4 input channels of 25Gb/s electrical data into 4 LAN WDM (wavelength division multiplexing) optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission along a single fiber. PSM4 and SR4 transceivers are not multiplexed and so require 4 parallel fibers, which are especially costly over distances of 2km to 10km. Although completing separate designs for TX (transmit), RX (receive) and combination TX-RX optical engines (see accompanying link to TX-only graphic), POET intends to focus first on the TX design, which offers significant cost and performance advantages, and represents a fast go-to-market approach for the Company.

Commenting on the new POET design for 100G LR4,
As the standard for interconnects to long-haul networks, 100G LR4 transceivers are purchased in high volumes by telecom equipment providers and are not being replaced by 400G transceivers even as speeds in long-haul networks increase. In an
Powering these optical engines will be 25Gb/s Directly Modulated Lasers (DML) from Sanan Integrated Circuits (SAIC), which has incorporated POET’s interposer compatibility requirements into their line of LR4 DML lasers. These lasers have been independently tested and validated to operate to LR4 specifications and are already in their qualification phase. SAIC will also be sourcing the monitor photodiodes and the high-speed photodiodes which rounds out the bill of materials for the optical engine. Assembly, manufacture and sales of these optical engines will be accomplished through POET’s joint venture with SAIC, Super Photonics Xiamen (SPX). SPX has accepted delivery of the first of a kind equipment set for the assembly of optical engines based on POET’s Optical Interposer and will be actively engaged in the assembly of POET’s Alpha optical engine prototypes later this quarter. POET and SPX are working with two Alpha customers today and the design win funnel has been active with increasing demand for both standard and custom designs for LR4 optical engines.
