ST202EBN Application Field and Working Principle

ST202EBN is a 2.5Gbps parallel optical fibre transceiver designed for data centre and enterprise applications. It is designed to provide a cost-effective solution for high-speed data-transmission over optical networks. The ST202EBN is a high performance transceiver that is capable of operating with data rates up to 2.5Gbps over multimode fibre. It is ideal for applications such as 10Gbps Ethernet, 10G Fibre Channel, 10G Passive Optical Networks (PONs), Sonet, and similar applications.

Application Fields

The ST202EBN transceiver is suitable for a wide range of applications in corporate data centers, enterprise networks, and storage-area networks. It provides a cost-effective solution for high-speed data transmission over optical networks. The transceiver includes a primary and auxiliary receiver and transmitter channels, allowing for full-duplex operation. This transceiver is fully compatible with the existing SFP+ infrastructure and is able to provide up to 2.5Gbps data transfer.

The ST202EBN transceiver is used in high-speed Ethernet over long distances and is ideal for data center, enterprise and storage-area networks. The ST202EBN transceiver supports 10G data rates over multimode fiber for up to 10km, enabling cost-effective fiber-based data connections.

The ST202EBN transceiver is also well-suited for 10G Passive Optical Network (GPON) based systems. GPON is a type of Ethernet implemented on Passive Optical Networks, which provides efficient transmission of 10Gbps data over long distances using existing fiber access networks. It is a digital network that uses WDM (Wavelength Division Multiplexing) technology to provide point-to-point connections between the customer and the network service provider(s).

The ST202EBN transceiver is also used in applications such as synchronous optical networking (SONET), which is a type of high-speed synchronous digital hierarchy (SDH) protocol used to carry voice, video, and other services over an optical fiber network. It provides an efficient and reliable way to transport voice, video, and data over long distances.

Working Principle

The ST202EBN transceiver contains two main optical transceiver components, the transmitter and the receiver. The transmitter is a combination of a vertical cavity surface emitting laser (VCSEL) and a modulator. The VCSEL is used to generate light pulses which are then modulated by the modulator depending on the data being transmitted. The receiver is a combination of a light detector and a trans-impedance amplifier. The light detector is used to detect the light pulses, which are then converted to electrical signal by the trans-impedance amplifier.

The signal is then split into a primary and auxiliary receiver sections. The primary receiver section processes and sends the data to the host system while the auxiliary receiver section is directly connected to an adjacent optical transceiver, allowing for full-duplex operation. In full-duplex operation both transceivers can send and receive data simultaneously.

The ST202EBN transceiver is designed with galvanic isolation, allowing for the transmission and reception of high-speed data over long distances with minimal signal degradation. The galvanic isolation is achieved by using an optical isolator which is placed between the transmitter and the receiver. The optical isolator is used to prevent any electrical interference from reaching the receiver and also to reduce any optical cross talk, which could interfere with the transmitted signal.
