|---|---|---|---|
| Basic Functions |
TOM supports various application scenarios, please refer to Application Overview for the introduction of each application scenario. |
||
| Customer-side Service Types |
FE: Ethernet service at a rate of 125 Mbit/s. GE: Ethernet service at a rate of 1.25Gbit/s. Supports GE optical or electrical signals. OTU1: OTN service at 2.67Gbit/s. STM-1/OC-3: SDH/SONET service at a rate of 155.52 Mbit/s STM-4/OC-12: SDH/SONET service at a rate of 622.08 Mbit/s STM-16/OC-48: SDH/SONET service at a rate of 2.5Gbit/s FC100: SAN service at a rate of 1.06 Gbit/s FC200: SAN service at 2.12 Gbit/s FICON: SAN service at 1.06Gbit/s FICON Express: SAN service at 2.12Gbit/s HD-SDI: high-definition digital TV service at 1.49 Gbit/s DVB-ASI: digital TV service at 270Mbit/s SDI: digital TV service at 270Mbit/s ESCON: SAN service at 200 Mbit/s FDDI: SAN service at a rate of 125 Mbit/s Description:
TOM single-board access to the GE signal, in order to facilitate the fiber, it is recommended to configure a maximum of two electrical modules, it is recommended to install the electrical module in the "RX1"/"TX1", "RX2"/"TX2". RX1"/"TX1" and "RX2"/"TX2" ports. TOM board supports access to SDI, HD-SDI, DVB-ASI signals, access requires the use of digital video photoelectric converter box, the optical module needs to meet the requirements of the single-board optical module indicators, the video converter box is a third-party device, you need to purchase their own. Only TN52TOM supports access to SDI, HD-SDI signals. |
