MEMS optical switch is one of the core devices in ROADM. Based on the demand for existing business and the demand for future network development, HYC has launched a series of independently developed MEMS technology products.
The upcoming 5G application promotes the upgrade of the all-optical network (AON). As a key part of the all-optical network, the ROADM market is expected to usher in rapid growth, especially in metropolitan area networks.
MEMS optical switch is one of the core devices in ROADM. Optical switch is a kind of optical path controlling device, with the ability to control and switch the optical path. MEMS fiber optic switches are based on micro-electro-mechanical system (MEMS) technology, which achieved low insertion loss and highly repeatability by rotating the mirror of MEMS chip.
Coupled with wavelength selective switch (WSS), MEMS fiber optical switches can configuration flexibility, wavelength independent (enables any wavelength to be added/dropped on any port), direction independent (receive multiple input wavelength channels in different directions), and no conflicts (the ability to download the same wavelength channel from different directions through the same switch). This is of great significance for the flexibility and low cost of network construction. A typical CDC-ROADM technology structure is shown in the figure.
With the rapid development of Internet applications the implementation of ROADM technology based on WSS (Wavelength Selective Switch) + MCS (Multi-Cast Switch) will become an ideal solution in the construction of metropolitan area networks. 1×N MEMS optical switch is an important part of MCS.
Based on the demand for existing business and the demand for future network development, HYC has launched a series of independently developed MEMS technology products, including 1×48 channel MEMS optical switch, MEMS optical switch module integrated with WDM, PLC or PD, and MCS module.
HYC’S 1×48 Optical Switch is based on MEMS (Micro Electro Mechanical System) technology and Free-space Platform. With the features of compact structure, low latency, efficient switching and other features, it is widely used in fiber monitoring system, optical add/drop system and measurement instrument system.
What is an OTDR and its basic working principle?
OTDR is an Optical Time-domain Reflectometer. It is the main devices in optical fiber measurement. It uses to test detect problems that may exist in fiber links.
What is C band and L band in WDM (Wavelength Division Multiplexing)?
According to the ITU-T standards, singlemode fiber with the band over 1260nm is divided into O/E/S/C/L/U six bands.What's the wavelength of these bands?
What are insertion loss and return loss?
In fiber optic communications, insertion loss and return loss are two important indicators. What are insertion loss and return loss? What causes the IL/RL? HYC can provide customized high-quality optical fiber connectors, optical fiber jumpers and other optical connection products according to customer needs.
