5G wireless transport constitutes the fundamental infrastructure underpinning the Internet of Everything and the digital economy. As 5G technologies are deeply deployed across three major service scenarios — enhanced Mobile Broadband (eMBB), Ultra‑Reliable Low‑Latency Communication (URLLC) and massive Machine‑Type Communication (mMTC) — transport networks are required to satisfy stringent specifications for ultra‑large bandwidth, ultra‑low latency, massive‑terminal access and high‑precision clock synchronization. Built upon the WDM wavelength‑division multiplexing architecture, the Optical Transport Network (OTN) features large bandwidth, low latency and flexible networking. It can cover the full link of 5G fronthaul, midhaul and backhaul, and support services such as base‑station interconnection, edge computing, cloud‑native core network and Industrial IoT. Market demand for optical transport solutions with low‑cost large bandwidth, hard‑isolated network slicing and end‑to‑end intelligent scheduling keeps surging.
Sunstar has in‑depth technology accumulation and full‑scenario product deployment capabilities in the 5G wireless‑transport sector. We deliver high‑performance, highly‑reliable interconnection solutions of optical elements, optical components and optical transceivers, including optical elements such as 50G EML TO‑CAN and 50G APD TO‑CAN; optical components such as 50G PAM4 ER BOSA, 100G TOSA/ROSA and 400G TOSA/ROSA; as well as optical‑transceiver products covering 25G wavelength‑tunable transceivers, 5G fronthaul modules, and 100G/400G coherent & non‑coherent transmission modules. Sunstar continuously meets the strict industry requirements for FlexE, simplified SRv6 protocol stack and high‑precision synchronization. We are also actively developing silicon‑photonics integration and low‑power optical‑interconnection technologies to fully enable the smooth evolution of 5G transport networks and converged bearing of multi‑services.
