QSFP-DD (Quad Small Form-Factor Pluggable Double Density) is a high-speed transceiver module that provides double the density of ports compared to traditional QSFP modules. QSFP-DD is designed to support various data rates depending on the specific variant. 200 Gigabit Ethernet (200GbE): QSFP-DD modules can support a data rate of 200 Gbps, allowing for high-speed network connections.400 Gigabit Et

AOC (Active Optical Cable) and DAC (Direct Attach Cable) are both types of cables used in data center and high-performance computing environments to connect networking equipment. While both serve similar purposes, there are key differences between the two: AOC (Active Optical Cable):Technology: AOCs use optical fibers to transmit data. They contain optical transceivers on each end of the cabl

CWDM4 (Coarse Wavelength Division Multiplexing 4) and FR1 (Frequency Range 1) are terms used in the context of optical communication, specifically in the development of 5G networks. They refer to different aspects of the communication infrastructure. CWDM4 (Coarse Wavelength Division Multiplexing 4):Wavelength Division Multiplexing (WDM): CWDM is a technology that allows multiple data streams

GPON (Gigabit Passive Optical Network) and BiDi (Bidirectional) refer to different technologies used in the field of fiber-optic communication, particularly in the context of passive optical networks. Here are the key differences between GPON and BiDi: GPON (Gigabit Passive Optical Network):Architecture: GPON is a point-to-multipoint optical access technology that uses a passive optical split

Transmitting Optical Sub-Assembly (TOSA) mainly plays the role of electrical signals into optical signals (E/O), to determine its performance indicators are mainly optical power, threshold.TOSA mainly consists of lasers (TO-CAN), adapters, tube core sets, in the long-distance optical module, will also join the isolator and adjusting the ring, the isolator to play a role in the role of anti-reflect
