The LevelOne SFP-9321 is a high performance, cost-effective SFP transceiver. It provides up to 1.25 Gbps bi-directional data transfer rate at distances up to 20km on a single fiber core. These bi-directional SFP Transceivers allow data transfer in either direction through a single optical fiber by employing separate wavelengths travelling in either direction.The SFP-9321 transmits using a wavelength of 1310nm and receives using a wavelength of 1550nm. When coupled with the LevelOne SFP-9331 transceiver which transmits at and receives at the opposite rates (1310nm TX and 1550nm RX) you get bi-direction data communication on a single fiber core.- 1310nm FP LD- Multi Data Rate: from 125M to 1.25Gbps, NRZ- Single +3.3V Power Supply- RoHS Compliant and Lead-free- AC/AC Differential Electrical Interface- Compliant with Multi-Source Agreement (MSA)- Simplex LC Connector- Compliance with specifications for IEEE-802.3z Gigabit Ethernet at 1.25Gbps- Compliance with ANSI specifications for Fiber- Channel applications at 1.06bps- No configuration or installation software required- Eye Safety Designed to meet LASER Class 1 comply with EN60825-1
