Short Description

QSFP28-100Gb/s SR4 150M DDM MultiMode

Application

  • 10GBASE-SR4 100G Ethernet

Compliance

  • QSFP28 MSA
  • IEEE802.3bm
  • SFF-8436
  • ROHS

This NETRO NN-QSFP28-100G-SR-02 are designed for use in 100 Gigabit Ethernet links over multimode fiber. They are compliant with the QSFP28 MSA and IEEE 802.3bm 100GBASE-SR4and CAUI-4. Module-level digital diagnostic functions are available via an I2C interface, as specified by the QSFP+ MSA. The optical transceiver is compliant per the RoHS Directive 2011/65/EU.

Note:

  1. Maximum total power value is specified across the full temperature and voltage range. when CDRs are locked or a lack of input signal results in squelch being activated. If incorrect frequencies cause the CDRs to continuously attempt to lock, maximum power dissipation may reach 4.5W.

Output voltage is settable in 4 discrete range via I2C.Default range is Range 2 (400 – 800mV).
