Description

This Arista 100GBASE-ZR4 QSFP (QSFP28) transceiver carries 100GbE up to 80km over duplex single-mode fibre with LC connectors. It suits long-haul data centre interconnect and metro or WAN links where the distance would otherwise need external DWDM or coherent optics.

Optically it uses four LAN-WDM lanes around 1310nm (1295.56, 1300.05, 1304.58 and 1309.14 nm) with a transmit power of +2 to +7 dBm per lane and a receive range of -5.0 to -28.0 dBm per lane. Maximum power consumption is 5.5W, the highest of the Arista 100G QSFP optics. Operating case temperature is 0 to 70 C.

The module is supported on a limited set of Arista platforms, with a minimum EOS of 4.26.2, and some platforms have airflow and ambient temperature limits. On shorter links, optical attenuation of at least 12dB is required to protect the receiver from permanent damage.

FAQs

Q: Does it need optical attenuation on short links?
A: Yes. Attenuation of at least 12dB is needed on shorter links to prevent permanent damage to the receiver.

Q: Which switches support this transceiver?
A: It is supported only on a limited set of Arista platforms. Check the Arista Transceiver and Cable Guide for the platform list, port restrictions and the minimum EOS of 4.26.2.

Q: What fibre and connector does it use?
A: It uses duplex LC connectors over single-mode fibre (SMF G.652), with a maximum reach of 80km.

Q: How much power does it draw?
A: Maximum power consumption is 5.5W per module, the highest of the Arista 100G QSFP optics. Some platforms have airflow and ambient temperature limits because of this.

Q: What optical power levels does it operate at?
A: Transmit power is +2 to +7 dBm per lane and the receive range is -5.0 to -28.0 dBm per lane across four LAN-WDM wavelengths around 1310nm.
