25G SFP28 transceiver modules are essential for modern networking, offering high-speed data transmission for various applications. Here are some common types and their features:

SR (Short Range)
– **Wavelength:** 850 nm
– **Distance:** Up to 300 meters over OM4 multimode fiber
– **Application:** Ideal for short-distance connections within data centers.

LR (Long Range)
– **Wavelength:** 1310 nm
– **Distance:** Up to 10 kilometers over single-mode fiber
– **Application:** Suitable for longer connections between buildings or across campus networks.

ER (Extended Range)
– **Wavelength:** 1550 nm
– **Distance:** Up to 40 kilometers over single-mode fiber
– **Application:** Used for long-haul connections requiring higher transmission distances.

ZR (Extended Reach)
– **Wavelength:** 1550 nm
– **Distance:** Up to 80 kilometers over single-mode fiber
– **Application:** Often employed in metropolitan area networks (MAN) for high-capacity links.

PAM4 (Pulse Amplitude Modulation)
– **Technology:** Uses PAM4 modulation for higher data rates
– **Distance:** Varies based on specific design (e.g., up to 25 km over single-mode)
– **Application:** Increasingly used in high-density data centers for improved bandwidth efficiency.

Active Optical Cable (AOC)
– **Type:** Integrated transceiver with fiber optic cable
– **Distance:** Typically up to 100 meters
– **Application:** Cost-effective for short connections, simplifying installation with pre-terminated cables.
