UTILIZE FOR:

SYROTECH  1G CWDM SFPs are used to provide a high-speed data rate of 1.25Gbps over a single wavelength on a standard single-mode fiber with a transmission distance of up to 40 KM. It is compliant with SFP MSA and SFF-8472 with a duplex LC receptacle for optical connectivity. with this CWDM technology, it is possible to multiplex multiple signals on a single fiber, which can provide significant cost and space savings in network deployments. Based on the market,syrotech SFPs are cost-effective and offer good compatibility with leading networking equipment.

Digital Diagnostic Memory Map

• A two-wire serial interface provides information about the present operating conditions and serial ID memory contents (SCL, SDA). 
• There are diagnostics with internal calibration or external calibration, including signals for received power, transmitted power, bias current, supply voltage, and temperature.
• Digital diagnostic memory map data fields are defined as follows.

Pin Description

Notes: 

Plug Seq.: Pin engagement sequence during hot plugging. 

1) A TX fault is an open collector output on the host board. It should be pulled up to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a laser fault. When the output is low, it is pulled to less than 0.8 volts. 

2) TX Disable allows you to disable the transmitter's optical output. This resistor is pulled up in the module by the 4.7k~10kΩ resistor. Typically, the sensor's states are: Low (0 to 0.8V): Transmitter on (>0.8V,-2.0V): Undefined High (2.0 to 3.465V): Transmitter Disabled Open: Transmitter Disabled

 3) Mod-Def 0,1,2 (module definition pins): 

Pull them up using a 4.7k~10kΩ resistor on the host board. It should be VccT or VccR for pull-up voltage. For serial ID, Mod-Def 0 is grounded by the module to indicate its presence; Mod-Def 1 is the clock line; Mod-Def 2 is the data line. 

4) LOS output is an open collector output that should be pulled up with a 4.7k~10kΩ resistor. Voltage should be pulled up between 2.0V and Vcc+0.3V. Loss of signal is indicated by logic 1; normal operation is indicated by logic 0. When the output is low, it will be pulled below 0.8V. 

5) RD-/+( Differential receiver outputs):- These outputs are 100 differential lines internally coupled to AC. They should be terminated with 100Ω (differential) at the user SERDES.

 6) TD-/+ ( Differential transmitter inputs):- The differential lines are internally AC-coupled and terminated with a 100Ω differential termination inside the module.
