Formerica Optoelectronics TAS-A1NS1-K11

This 10Gigabit SFP+ transceiver, based on a 1550nm cooled EML laser, is designed to transmit and receive optical data over single-mode fiber with link lengths up to 40km. The SFP+ ER module's electrical interface complies with the SFI electrical specification. Transmitter input and receiver output impedance is 100 ohm differential. Data lines are internally AC-coupled. The module provides differential termination and reduces differential-to-common-mode conversion for high-quality signal termination and low EMI. SFI typically operates over 200mm of enhanced FR-4 material, or over standard FR-4 with one connector up to approximately 150mm in length. The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 10GBASE-LR standard. An open-collector compatible Transmit Disable (Tx_Dis) function is provided. When this pin is logic "1" or left unconnected, laser transmission is disabled. When this pin is logic "0", the laser operates normally. The transmitter incorporates an internal automatic power control (APC) loop to ensure constant optical output power over variations in supply voltage and temperature. An open-collector compatible Transmit Fault (Tx_Fault) function is provided. TX_Fault is a module output contact that, when asserted high, indicates the module transmitter has detected a fault condition related to laser operation or safety. The TX_Fault output contact is open-drain/collector and should be pulled up to the host's Vcc_Host through a resistor in the range of 4.7–10kΩ. TX_Disable is a module input contact. When TX_Disable is asserted high or left floating, the SFP+ module transmitter output will be shut down. This contact should be pulled up to VccT through a resistor of 4.7kΩ to 10kΩ. The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data. An open-collector compatible Loss of Signal (Rx_LOS) function is provided. When Rx_LOS is asserted high, it indicates that the optical signal level is below the value specified by the relevant standard. The Rx_LOS contact is an open-drain/collector output and should be pulled up to the host's Vcc_Host through a resistor in the range of 4.7–10kΩ, or use active termination. Power supply filtering for both the transmitter and receiver is recommended. The Rx_LOS signal is intended to provide the system hosting the SFP+ with a preliminary indication that the received signal strength is below the specified range. This indication typically suggests that the cable is not installed, the cable is damaged, or the transmitter at the far end of the cable is disabled, faulty, or powered down.
