賽勒科技 | 高速硅光引擎助力Semtech 800G LPO方案

  ICC訊 2025年4月1日，南通賽勒光電科技有限公司(以下簡稱“賽勒科技“)宣布，其針對AI集群和數(shù)據(jù)中心設(shè)計(jì)的高性能800G硅光引擎產(chǎn)品將在美國舊金山舉行的2025年度光纖通信大會(OFC)期間展示，展會時(shí)間為4月1日-4月3日。賽勒科技的800G高速光引擎將會以800G高速光模塊(OSFP800)的形式，在合作伙伴Semtech公司的展位展出(展位號為1028)。Semtech現(xiàn)場展示的800G LPO光模塊采用了賽勒科技——高性能800G硅光引擎。

  該引擎集成了高速硅光調(diào)制器芯片，光纖整列，以及兩個(gè)連續(xù)波(CW)激光器，每個(gè)激光器可支持四個(gè)通道。800G硅光調(diào)制器芯片集成了多個(gè)調(diào)制器、分光器、MPD、波導(dǎo)和耦合結(jié)構(gòu)，可以對8個(gè)單通道為100Gb/s PAM4信號進(jìn)行高速的光學(xué)調(diào)制。

  現(xiàn)場展示的800G LPO光模塊被放在交換機(jī)不同的位置進(jìn)行系統(tǒng)驗(yàn)證。其性能充分滿足IEEE P802.3df D2.0對800GBASE-DR8的光接口規(guī)范要求。誤碼率水平尤其出色，即使在較長路徑的位置(系統(tǒng)插損16dB)也實(shí)現(xiàn)了e-11誤碼率水平，在較短路徑的位置(系統(tǒng)插損8dB)，則可以實(shí)現(xiàn)e-13誤碼率水平。

  Shanghai, Apr.01, 2025 – SiLUX Technologies Inc. (“SiLUX”), the designer and developer of silicon Photonic Integrated Circuits (PICs) and optical engines for the data center and telecommunication markets, today announced that a live demonstration of its 800G optical engine will take place together with Semtech (Booth #1028) in OSFP800 form factor during the upcoming OFC’25 Conference in San Francisco, CA from Apr.01 – Apr. 03, 2025.

  The 800G linear-drive pluggable optics (LPO) demoed by Semtech are integrated with SiLUX's novel high performance silicon photonics (SiPho) optical engine, which incorporates SilUX’s Silicon Photonic Modulator PIC with two continuous wave (CW) lasers that each supports four lanes. The 800G Sipho Modulator PIC monolithically integrates multiple modulators, splitters, MPD, waveguides and coupling structures, enabling high-speed modulation of light operating at 100Gb/s PAM4 signaling for data transmission.

  These modules have been put in different slots to validate performance. Overall results exceed the optical interface specifications of IEEE P802.3df D2.0 for 800GBASE-DR8 significantly, especially very good BER even in long port e-11@16dB system loss and e-13@8dB system loss.
