How Much Do You Know About 100G Optical Transceivers?
Amid explosive growth in data traffic and rapid popularization of computing power networks, 100G optical transceivers have become core transmission hardware for data centers, 5G communications, backbone transmission networks and other scenarios. As the most widely used high-speed optical communication component today, it supports the core transmission links of modern high-speed networks with its advantages of high bandwidth, low latency and high density.
I. Common Categories of 100G Optical Transceivers
Currently, mainstream 100G optical transceivers adopt the QSFP28 package. Based on transmission distance, fiber type and technical solution, they are mainly divided into the following categories:
-
100G SR4Multi-mode short-range optical transceiver with a wavelength of 850nm and a transmission distance of approximately 100 meters. It features cost efficiency and high deployment density, making it the standard solution for internal interconnection in data centers.
-
100G LR4Single-mode medium-range optical transceiver with a wavelength of 1310nm and a standard transmission distance of 10km. It delivers high stability and is suitable for campus interconnection, metropolitan access and medium-range 5G base station backhaul.
-
100G ER4Single-mode long-haul optical transceiver with a transmission distance of up to 40km, mostly used for metropolitan area network backbones, cross-regional data center interconnection and other medium-to-long-haul scenarios.
-
100G ZR4 / 100G 80kmUltra-long-haul single-mode optical transceiver with a transmission distance of up to 80km and strong attenuation resistance. It is mainly used for provincial trunk lines, inter-city backbone networks and other core long-haul transmission scenarios.
In addition, there are specialized models such as 100G CWDM4 and 100G PSM4 to meet the diversified networking needs of operators and equipment manufacturers.
II. Main Application Scenarios of 100G Optical Transceivers
With excellent transmission performance, 100G optical transceivers have been widely deployed in mainstream high-speed communication fields:
- High-speed interconnection between servers and switches in hyperscale data centers
- Fronthaul, midhaul and backhaul core links of 5G base stations
- Enterprise core backbone networks and cross-building fiber interconnection in campuses
- Carrier-grade metropolitan area networks and provincial long-haul transmission networks
- High-bandwidth, low-latency key business scenarios such as finance, cloud computing and AI computing power centers
