Frequently Asked Questions (FAQ)
What is the difference between SR4 and LR4 QSFP+ transceivers?
QSFP+ SR4 (Short Range) transceivers operate over multi-mode fiber (MMF) at 850nm, supporting distances up to 100m or 400m via MPO connectors. In contrast, QSFP+ LR4 (Long Range) transceivers operate over single-mode fiber (SMF) using CWDM wavelengths (1270-1330nm), supporting distances up to 10km or 20km via LC duplex connectors.
Which connector types are supported by these 40G QSFP+ modules?
These modules support either MPO or LC connectors depending on the model. Generally, parallel multi-mode transceivers (like SR4 and ESR4) use MPO connectors, while wavelength-division multiplexing (WDM) single-mode transceivers (like CWDM4, LR4, ER4, and ZR4) use LC duplex connectors.
What is the maximum transmission distance achievable with these modules?
The transmission distance ranges from 100 meters (using SR4 multi-mode fiber) up to 80 kilometers (using the ZR4 model, which operates over single-mode fiber with a DFB+APD laser configuration).
What is the operating temperature range for these QSFP+ transceivers?
All listed QSFP+ modules are rated for standard commercial operating temperatures ranging from 0°C to 70°C (32°F to 158°F), making them suitable for most standard data center and enterprise networking environments.
What is the difference between PIN and APD receivers in these modules?
PIN photodetectors are typically used for short to medium-range transmissions (up to 40km) due to their simpler design and lower cost. APD (Avalanche Photodiode) receivers offer much higher sensitivity, allowing them to detect weaker optical signals, which is why they are utilized in long-range modules like eER4 (60km) and ZR4 (80km).
