Frequently Asked Questions
Q:What is the difference between standard SFP, SFP BIDI, and SFP CWDM?
Standard SFP modules use dual fibers (one for transmitting and one for receiving). SFP BIDI (Bi-Directional) transceivers utilize a single fiber to transmit and receive signals at different wavelengths simultaneously. SFP CWDM modules operate at specific wavelengths (from 1470nm to 1610nm) to multiplex multiple data channels over existing fiber lines.
Q:What do the "T" and "R" values represent in the wavelength column for BIDI modules?
"T" stands for Transmit wavelength, and "R" stands for Receive wavelength. For example, "T13/R15" indicates that the module transmits data at 1310nm and receives data at 1550nm. These modules must always be used in complementary pairs (e.g., pairing a T13/R15 module with a T15/R13 module).
Q:Are these SFP optical transceivers hot-pluggable?
Yes, all the listed SFP transceivers are fully hot-pluggable. This allows you to install or replace the modules without powering down your switches or network devices, ensuring uninterrupted network uptime.
Q:What is the difference between PIN and APD receiver types?
PIN receivers are standard photodetectors suitable for short to medium-distance transmissions. APD (Avalanche Photodiode) receivers feature high optical sensitivity and internal gain, making them ideal for long-distance applications (such as 80KM and 120KM) where signal attenuation is high.
Q:Do these SFP modules support Digital Diagnostics Monitoring (DDM)?
Yes, the "D" suffix at the end of the Part Numbers (e.g., ESP8524-03D) indicates support for DDM/DOM functions. This feature allows real-time monitoring of critical parameters such as optical output power, input power, temperature, and laser bias current.
Q:Can these modules operate in harsh environmental temperatures?
The standard models listed support a commercial operating temperature range of 0°C to 70°C. If your application requires industrial-grade temperature support (-40°C to 85°C), please contact our sales team for customized solutions.
