SR4

SR4

SR (Short Range):

The term “SR” indicates that the transceiver is designed for short-distance data transmission. SR transceivers typically use multimode fiber (MMF) and are optimized for shorter reach applications within data centers.

4 (in SR4)

The “4” in SR4 signifies that the transceiver uses four parallel lanes of data transmission. Each lane typically operates at 25G or 50G, depending on the specific transceiver, resulting in a total of 100G or 200G for SR4.

Key Characteristics of SR4:

  • Fiber Type: Multimode fiber (MMF), typically OM3 or OM4.
  • Reach: Typically supports up to 100 meters (OM3) or 150 meters (OM4) on multimode fiber.
  • Applications: Ideal for short-range, high-bandwidth connections within a data center.
