    Specifications

    Cisco QSFP-40/100-SRBD Compatible 40/100GBASE-SWDM4 QSFP28 Optical Transceiver Module (850nm & 900nm MMF 100m LC DDM)

     

    The Cisco QSFP-40/100-SRBD compatible 40G/100G QSFP28 BIDI module is a versatile optical solution, supporting both 40Gb/s and 100Gb/s bit rates. This module, designed in a parallel Quad Small Form-factor Pluggable (QSFP28) Bi-Directional format, efficiently integrates four host electrical data streams into two optical lanes. It achieves this through the use of Dual Wavelength VCSEL Bi-Directional Optical Interface, utilizing wavelengths at 850nm and 900nm. This innovative design enables seamless optical communication over a 2-fiber duplex LC optical multi-mode fiber.

      Got this 40/100G SRBD optics for our Cisco Nexus 93180YC-FX switches. Needed it for a 100G link upgrade and it's been spot on - no issues at all. Really chuffed with the performance and the price was decent for a compatible module. Proper good value!

      These modules have arrived with decent packages and solid build. Worked flawlessly with reliable connectivity. However, if they can provide a local pick up service, it would be more convenient for our company.
