Specifications

Generic Compatible 400G OSFP DR4 PAM4 Silicon Photonics Optical Transceiver Module (1310nm, 500m, MPO-12 APC Connectors, SMF, 0℃ to +70℃, DOM)

 

The QSFPTEK QT-OSFP-400GSi-DR4 is a transceiver module designed for 500m optical communication applications, and it is compliant with OSFP MSA and IEEE 802.3bs protocol. The silicon photonics transceiver is based on a new state-of-the-art silicon photonics (SiPh) platform. It uses SiPh chips that integrate a number of active and passive optoelectronic components, 3D packaging technology and industry-leading 7nm DSP chips. It is a cost-effective and lower power consumption solution for a 400GBASE data center. It has been designed to meet the harshest external operating conditions, including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.

  • 400G OSFP (6)
  • 400G QSFP-DD (2)
  • QT-OSFP-400G-SR8 (3)
  • QT-OSFP-400G-DR4 (1)
  • QT-OSFP-400G-SR4 (1)
  • Can I plug an OSFP optical module to a QSFP-DD port?
    No. QSFP-DD and OSFP are two different form factors and they have completely different shapes and sizes. You can only use one kind of form factor in the corresponding system, for example, if you use OSFP system, then you must use OSFP transceiver and cable.
  • Can I plug a QSFP28 optical module to a OSFP port?
    Yes, but you need to use an adapter. When inserting a QSFP28 module into an OSFP port, the OSFP port must be configured for 100G instead of 400G transmission rate
  • What 400G form-factors does QSFPTEK support?
    QSFPTEK support OSFP and QSFP-DD form factor. QSFPTEK 400G platform can offer OSFP and QSFP-DD variants, OSFP form factor include OSFP-400G-LR8, OSFP-400G-DR4, OSFP-400G-SR8, QSFP-DD form factor include QSFP-DD-DR4, QSFP-DD-FR4, QSFP-DD-SR8, QSFP-DD-LR8, QSFP-DD-ER8, QSFP-DD-4x100G-LR.
