    H3C QSFP-40G-ER4-WDM1300 Compatible 40G QSFP+ ER4 Transceiver Module (1310nm SMF 40km LC DDM)

     

    The QSFPP-40G-ER4 transceiver module is designed for optical communication over distances of up to 40 kilometers, in compliance with the IEEE P802.3ba 40GBASE-ER4 standard. This module efficiently converts four 10Gb/s electrical data input channels into individual CWDM optical signals, which are then multiplexed into a single 40Gb/s optical transmission channel. Similarly, on the receiving end, it demultiplexes a 40Gb/s input signal into four CWDM channels, converting them into a four-channel electrical data output. This bidirectional capability ensures reliable communication over extended distances.

    Questions & Answers

    • All (8)
    • Can this module work at 80°C?
      No, it can't. The working temperature range is 0 to 70°C.
    • Does the qsfp-40g-sr4 transceivers allow 4x 10g connectivity?
      Yes. The connectivity is achieved by using an 8-fibers OM4 MTP-LC Type B break-out cable, which connects the qfp-40g-sr4 transceivers to four sfp-10g-sr optical interfaces.
    • What is the difference between Cisco qspf-40g-lr4 and qsfp-40g-lr4-s?
      They are actually the same one.
