GENERAL DESCRIPTION
This 850 nm VCSEL 10Gigabit SFP+ transceiver is designed to transmit and receive optical data over50/125 µm or 62.5/125 µm multimode optical fiber (Table 1).
The SFP+ SR module electrical interface is compliant to SFI electrical specifications. The transmitterinput and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled.The module provides differential termination and reduce differential to common mode conversionfor quality signal termination and low EMI. SFI typically operates over 200 mm of improved FR4material or up to about 150mmof standard FR4 with one connector.
The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial optical data compliantwith the 10GBASE-SR standard. An open collector compatible Transmit Disable (Tx_Dis) is provided.A logic “1,” or no connection on this pin will disable the laser from transmitting. A logic “0” on thispin provides normal operation. The transmitter has an internal automatic power control loop (APC)to ensure constant optical power output across supply voltage and temperature variations. An open collector compatible Transmit Fault (Tx_Fault) is provided. TX_Fault is a module output contact that when high, indicates that the module transmitter has detected a fault condition related to laser operation or safety. The TX_Fault output contact is an open drain/collector and shall be pulled up to the Vcc_Host in the host with a resistor in the range 4.7-10 k . TX_Disable is a module input contact. When TX_Disable is asserted high or left open, the SFP+ module transmitter output shall be turned
off. This contact shall be pulled up to VccT with a 4.7 k to 10 k resistor.
The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data. An open collector compatible Loss of Signal is provided. Rx_LOS when high indicates an optical signal level below that specified in the relevant standard. The Rx_LOS contact is an open drain/collector output and shall be pulled up to Vcc_Host in the host with a resistor in the range 4.7-10 k , or with an active termination. Power supply filtering is recommended for both the transmitter and receiver. The Rx_LOS signal is intended as a preliminary indication to the system in which the SFP+ is installed that the received signal strength is below the specified range. Such an indication typically points to non-installed cables, broken cables, or a disabled, failing or a powered off transmitter at the far end of the cable.
