Frequently Asked Questions
What is a CWDM SFP transceiver?
A Coarse Wavelength Division Multiplexing (CWDM) Small Form-factor Pluggable (SFP) is a hot-swappable optical transceiver that uses CWDM technology to combine multiple optical signals on different wavelengths over a single fiber strand, optimizing network capacity.
What wavelengths do these CWDM SFP modules support?
These modules support wavelengths ranging from 1270nm to 1450nm (for the 40km variant) and 1470nm to 1610nm (for the 80km and 120km variants), allowing flexible channel planning.
What is the difference between PIN and APD receivers in these modules?
PIN receivers are suitable for standard and medium-distance transmissions (up to 80km), while APD (Avalanche Photodiode) receivers offer higher sensitivity (down to <-32dBm), making them ideal for long-distance transmissions up to 120km.
Are these CWDM SFPs hot-pluggable?
Yes, they are hot-pluggable, allowing network administrators to install or replace the transceivers without powering down the host system, ensuring uninterrupted network uptime.
What connector type and operating temperature range do these modules use?
These modules feature a standard Duplex LC connector and are designed to operate within a commercial temperature range of 0°C to 70°C.
Do these modules support Digital Diagnostic Monitoring (DDM)?
Yes, these modules feature built-in DDM/DOM capabilities, allowing real-time monitoring of parameters such as optical output power, input power, temperature, and transceiver supply voltage.
