What is the exact optical power budget and typical receiving sensitivity for this 80km 2.5G BiDi module? We are designing a long-haul rural link.

The transmitter optical power (TX) ranges from -2dBm to +4dBm, and the receiver sensitivity (RX) is down to -26dBm, which easily supports stable transmission up to 80km over standard Single-Mode Fiber (SMF) with normal safety margins.

Are these LINK-PP LS-BL49552G-80C transceivers fully compatible with Cisco and MikroTik switches out of the box, or do I need to specify custom EEPROM coding when ordering?

Yes, they come pre-coded with multi-vendor compatibility or specific OEM coding upon request (Cisco, MikroTik, Juniper, Ubiquiti, HP, etc.). Just leave a note during checkout regarding your switch brand so our technicians can pre-program the EEPROM.

Does this SFP module support real-time Digital Diagnostic Monitoring (DDM/DOM) so we can monitor temperature, optical power, and voltage via SNMP?

Absolutely. The LS-BL49552G-80C features built-in DDM/DOM functionality complying with SFF-8472 MSA standards. You can monitor real-time parameters such as transceiver temperature, laser bias current, transmitted optical power, and received optical power directly from your switch CLI or network management system.

I bought these 10/25/40G Transceiver Modules together with the recommended Lan Transformer. They help me select the right Polarity and show me their setup, and I received them very soon, much Faster than ever shopping. Nothing wrong with these items, they are built well and function well.
