❓Frequently Asked Questions (FAQ)
What is the difference between QSFP+ SR4 and LR4 optical transceivers?
QSFP+ SR4 (Short Range) transceivers operate at 850nm over multi-mode fiber (MMF) for distances up to 100m or 400m (ESR4), utilizing MPO connectors. In contrast, QSFP+ LR4 (Long Range) transceivers operate at CWDM wavelengths (1270-1330nm) over single-mode fiber (SMF) for distances up to 10km or 20km, using LC duplex connectors.
Which connector types are supported by these 40G QSFP+ modules?
Depending on the model, these modules support either MPO connectors (typically for multi-fiber parallel applications like SR4, ESR4, and PSM IR4) or LC duplex connectors (used for wavelength-division multiplexing applications like CWDM4, LR4, ER4, ZR4, Bidi, and SWDM4).
What is the maximum transmission distance supported by these transceivers?
The maximum transmission distance ranges from 100m over multi-mode fiber (using SR4 or Bidi modules) up to 80km over single-mode fiber using the EQP294X-80D QSFP+ ZR4 module equipped with a DFB+APD configuration.
Do these 40G QSFP+ transceivers support industrial operating temperatures?
All the models listed in this ordering information sheet are designed for standard commercial operating temperature ranges of 0°C to 70°C (0~70℃).
What is the difference between VCSEL and DFB/EML laser types in these modules?
VCSEL lasers are cost-effective light sources used for short-range multi-mode fiber transmissions (e.g., SR4). DFB (Distributed Feedback) and EML (Electro-absorption Modulated Laser) lasers provide narrower spectral widths and higher power output, making them ideal for long-distance single-mode fiber transmissions ranging from 2km up to 80km.
