The SFP GBIC-104 module is designed to convert an electrical signal into an optical signal. It is designed for single mode fiber transmission (SM) using one optical fiber terminated with an SC optical connector. Fiber type: single mode (SM) – 8.3/125?m, 8.7/125?m, 9/125?m, 10/125?m. Transmission speed: 1,25Gb/s. Transmission range: up to 20km. Optical Connector Type: 1xSC. Wavelength Tx/Rx: 1550nm / 1310nm. Standards and protocols: IEEE 802.3z 1000Base-FX. Power supply: 3,3VDC (power from SFP port). Built-in DDM (Digital Diagnostics Monitoring). The module has a snap-lock system for optical connectors. Proper communication with other devices requires the use of the GBIC-103 module.
