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 modules on a single 2-wire interface bus. When the ModSelL is "High", the module shall not respond to or acknowledge any 2-wire interface communication from the host.
ModSelL signal input node shall be biased to the "High" state in the module. In order to avoid conflicts, the host system shall not attempt 2-wire interface communications within the ModSelL de-assert time after any modules are deselected. Similarly, the host shall wait at least for the period of the ModSelL assert time before communicating with the newly selected module. The assertion and de-asserting periods of different modules may overlap as long as the above timing requirements are met.
Notice: It has to be noted that the operation in excess of any individual absolute maximum ratings might cause permanent damage to this module.

The ModSelL is an input pin. When held low by the host, it allows the module to respond to 2-wire serial communication commands. It enables multiple modules to share a single 2-wire interface bus.
This transceiver supports a link distance of up to 80km over Single Mode Fiber (G.652 SMF), assuming a typical fiber insertion loss of 0.35dB/km.
The absolute maximum storage temperature range is -40°C to 85°C, and the power supply voltage range is -0.3V to 4.0V. Operating beyond these thresholds may cause permanent damage to the device.
The module utilizes a LAN WDM EML laser transmitter and a highly sensitive PIN receiver integrated with a Semiconductor Optical Amplifier (SOA) to achieve high-performance long-reach transmission.
Yes, the transceiver supports three operating case temperature options: Commercial (0 to +70°C), Extended (-10 to +80°C), and Industrial (-40 to +85°C) to fit various environment requirements.
Yes, DDM (Digital Diagnostic Monitoring) is fully supported, allowing real-time monitoring of critical operating parameters such as transceiver temperature, laser bias current, optical power, and supply voltage.
