A brief summary of 100G QSFP options

100G QSFPs (quad small form-factor pluggable) are high-speed, compact and versatile optical transceivers that enables data transmission at 100 gigabits per second. It is a hot-swappable device that can be easily inserted into and removed from networking equipment without interrupting the system. The 100G QSFP or QSFP28 is available in various options that cater to different applications and data transmission requirements. Some of the most common options are below:

  1. 100G QSFP28 LR4: This option provides 100Gbps of data transmission over single-mode fibre (SMF) with a reach of up to 10km. It is ideal for datacentre interconnects, backbone networks, and long-haul data transmission applications. Fibrenet can also offer a 20km version of the LR4 which provides a good bridge between the LR4 and ER4 and is more cost effective than the ER4, of course.
  2. 100G QSFP28 SR4: This option provides 100Gbps of data transmission over multimode fibre (MMF) with a reach of up to 100 meters. It is ideal for high-density datacentres and short-haul data transmission applications.
  3. 100G QSFP28 CWDM4: This option provides 100Gbps of data transmission over CWDM (Coarse Wavelength Division Multiplexing) optical fibres with a reach of up to 2km. It is ideal for datacentre interconnects, service provider networks, and data transmission applications that require multiple wavelengths.
  4. 100G QSFP28 PSM4: This option provides 100Gbps of data transmission over parallel single-mode fibre (PSMF) with a reach of up to 500 meters. It is ideal for high-density datacentres and short-haul data transmission applications. The PSM4 is often used to break out to 4 x 25G singlemode SFP28 and can also breakout from 40G to 4 x 10G.
  5. 100G QSFP28 ER4: This option provides 100Gbps of data transmission over single-mode fibre (SMF) with a reach of up to 40km. It is ideal for long-haul data transmission applications that require high bandwidth and low latency.
  6. 100G QSFP28 ZR4: This option provides 100Gbps of data transmission over single-mode fibre (SMF) with a reach of up to 80km. It is ideal for ultra-long-haul data transmission applications that require high bandwidth and low latency.

These options provide flexible and cost-effective solutions for various data transmission requirements. The 100G QSFP28 is interoperable with other QSFP28 transceivers and is compatible with existing and emerging datacentre and network infrastructure.

In conclusion, the 100G QSFP offers multiple options for high-speed data transmission with different reaches, wavelengths, and fibre types to cater to various applications and requirements. These options provide cost-effective solutions that support the growing demand for high-speed data transmission and enable organizations to achieve their networking goals.
