Overview
ARIA’s 10Gbps 300m Range 850nm SFP+ Optical
Transceiver is designed to transmit and receive optical data
over 50/125 μm or 62.5/125 μm multi mode optical fiber (see
table below).
The transceiver module is comprised of a transmitter with an
850nm VCSEL and receiver with a PIN photo detector.
The transmitter converts 10Gb/s serial PECL or CML electrical
data into serial optical data compliant with the 10GBASE-SR
standard.
The receiver converts 10Gb/s serial optical data into serial
PECL/CML electrical data.
The module provides differential termination and reduces
differential to common mode conversion for quality signal
termination and low EMI.

Description
The SFP+ SR module electrical interface is compliant to SFI electrical specifications.
The transmitter input and receiver output impedance is 100Ω differential.
Data lines are internally AC coupled.
SFI typically operates over 200mm of improved FR4 material or up to about 150mm of standard FR4 with one connector.
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 this pin 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 (TFault) 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 kΩ.
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 4.7-10kΩ resistor.
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 kΩ, 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.

Notes:
1. Module circuit ground is isolated from module chassis ground within the module.
2. Should be pulled up with 4.7kΩ-10kΩ on host board to a voltage between 3.15V and 3.6V.
3. Tx_Disable is an input contact with a 4.7kΩ-10kΩ pullup to VccT inside the module.
4. Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a
resistor in the range 4.7kΩ-10kΩ. Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.
5. RS0 and RS1 are module inputs and are pulled low to VeeT with > 30 kΩ resistors in the module.
