Other Pin Descriptions:
ModSelL Pin
The ModSelL is an input pin. When held low by the host, the module responds to 2-wire serial communication commands. The ModSelL allows the use of multiple QSFP modules on a single 2-wire interface bus. When the ModSelL is “High”, the module will not respond to any 2-wire interface communication from the host. ModSelL has an internal pull-up in the module.
ResetL Pin
Reset. LPMode_Reset has an internal pull-up in the module. A low level on the ResetL pin for longer than the minimum pulse length (t_Reset_init) initiates a complete module reset, returning all user module settings to their default state. Module Reset Assert Time (t_init) starts on the rising edge after the low level on the ResetL pin is released. During the execution of a reset (t_init) the host shall disregard all status bits until the module indicates a completion of the reset interrupt. The module indicates this by posting an IntL signal with the Data_Not_Ready bit negated. Note that on power up (including hot insertion) the module will post this completion of reset interrupt without requiring a reset.
LPMode Pin
Rayoptek PSM IR4operate in the low power mode (less than 1.5 W power consumption) This pin active high will decrease power consumption to less than 1W.
ModPrsL Pin
ModPrsL is pulled up to Vcc on the host board and grounded in the module. The ModPrsL is asserted “Low” when the module is inserted and deasserted “High” when the module is physically absent from the host connector.
IntL Pin
IntL is an output pin. When “Low”, it indicates a possible module operational fault or a status critical to the host system. The host identifies the source of the interrupt by using the 2-wire serial interface. The IntL pin is an open collector output and must be pulled up to Vcc on the host board.
Power Supply Filtering
Optical Interface Lanes and Assignmen
The optical interface port is a male MPO connector .The four fiber positions on the left as shown in below, with the key up, are used for the optical transmit signals (Channel1 through4). The fiber positions on the right are used for the optical receive signals(Channel 4 through 1). The central four fibers are physically present.
