Transceiver koheren kini dianggap sebagai calon yang menjanjikan untuk menaik taraf transceiver 400Gigabit Ethernet (400GbE) semasa kepada 800G. Walau bagaimanapun, disebabkan oleh struktur rumit modulator IQ dwi-polarisasi (DP-IQM) dengan pembahagi/penyikat rasuk polarisasi yang besar (PBS/PBC), peningkatan dalam saiz dan kos pemancar tidak dapat dielakkan. Dalam kertas ini, kami mencadangkan struktur pemancar bebas PBS/PBC padat dengan konfigurasi garis lurus. Dengan menggunakan konsep modulasi pembezaan polarisasi, pemancar yang dicadangkan mampu menghasilkan isyarat DP fasa-shift-keyed (DP-PSK), yang menjadikannya terpakai terus kepada sistem koheren semasa. Analisis terperinci prestasi sistem mendedahkan bahawa penyamaan yang tidak sempurna dan had lebar jalur pada penerima adalah faktor penalti yang dominan. Walaupun penalti sedemikian biasanya tidak boleh diterima dalam aplikasi jarak jauh, pemancar yang dicadangkan boleh menarik kerana kesederhanaan dan kekompakan yang ketara untuk aplikasi jarak dekat, di mana kos dan jejak adalah kebimbangan utama.

Abstract: Coherent transceivers are now regarded as promising candidates for upgrading the current 400Gigabit Ethernet (400GbE) transceivers to 800G. However, due to the complicated structure of a dual-polarization IQ modulator (DP-IQM) with its bulky polarization-beam splitter/comber (PBS/PBC), the increase in the transmitter size and cost is inevitable. In this paper, we propose a compact PBS/PBC-free transmitter structure with a straight-line configuration. By using the concept of polarization differential modulation, the proposed transmitter is capable of generating a DP phase-shift-keyed (DP-PSK) signal, which makes it directly applicable to the current coherent systems. A detailed analysis of the system performance reveals that the imperfect equalization and the bandwidth limitation at the receiver are the dominant penalty factors. Although such a penalty is usually unacceptable in long-haul applications, the proposed transmitter can be attractive due to its significant simplicity and compactness for short-reach applications, where the cost and the footprint are the primary concerns.
