Description

This Arista 100GBASE-XCWDM4 QSFP28 transceiver carries 100G Ethernet up to 10km over duplex single-mode fibre with LC connectors. It suits 100G data centre interconnect and campus or metro links where the 2km reach of standard CWDM4 optics falls short.

The module is dual rate, supporting both 100G and 40G operation, which helps with gradual migration from 40G to 100G on the same ports. Optical output is -6.5 to +2.5 dBm per lane and receive power is -13 to +2.5 dBm per lane, over G.652 single-mode fibre. Maximum power consumption is 3.5W, drawn from the host switch port. The housing measures 13.5 x 18.4 x 72.4 mm and is rated for an operating case temperature of 0 to 70 C.

It fits Arista QSFP and QSFP28 ports and follows the 100G CWDM4 MSA, SFF-8636 and SFF-8449 standards. It is the longer-reach 10km sibling of QSFP-100G-CWDM4.

FAQs

Q: How does this differ from QSFP-100G-CWDM4?
A: This XCWDM4 module reaches up to 10km over duplex single-mode fibre, while the standard CWDM4 module is limited to 2km. Both follow the CWDM4 family on LC duplex single-mode fibre.

Q: Does it support 40G as well as 100G?
A: Yes. It is a dual rate 100G/40G module, which allows a gradual move from 40G to 100G.

Q: What fibre and connector does it use?
A: It uses duplex single-mode fibre (G.652) with LC connectors.

Q: What ports does it fit and how much power does it draw?
A: It fits Arista QSFP and QSFP28 ports. Maximum power consumption is 3.5W, supplied by the host switch port.

Q: Is the module hot swappable?
A: Yes. It can be inserted or removed while the switch is running.
