These are Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the VCSEL laser and the PIN photo-detector. The module data link up to 550m in 50/125um multi mode fibre.   The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.FEATURES Up to 1.25Gb/s data links with DDM VCSEL laser transmitter and PIN photo-detector Hot-pluggable SFP footprint Duplex LC/UPC type pluggable optical interface Low power dissipation Metal enclosure, for lower EMI RoHS compliant and lead-free Single +3.3V power supply Compliant with SFF-8472 Case operating temperature Commercial: 0°C to +70°C Extended:  -10°C to +80°C Industrial: -40°C to +85°C APPLICATIONS 1x Fibre Channel Switch to Switch Interface Gigabit Ethernet Switched Backplane Applications Router/Server Interface Other Optical Links WARRANTY3-years limited warrantyTAA-approved SFPs available upon request, Contact us for more details.
