Description

The QSFP-AMP-ZR is a hot-pluggable QSFP optical amplifier module from the Arista 400ZR DCI solution. It integrates a booster amplifier and a pre-amplifier, two micro-EDFAs in one pluggable, so data centre teams can run point-to-point interconnects over dark fibre using in-router DWDM instead of dedicated optical transport hardware.

The module supports 1 to 8 x 400ZR channels, up to 3.2T per fibre pair, at 200 GHz channel spacing across 192.900 THz to 194.500 THz. Booster gain is 25 dB and pre-amp gain is adjustable from 2 to 21 dB, enabling reach of up to 120km over single-mode fibre. Maximum power consumption is 4 W. This QSFP version uses duplex CS connectors on both the line and client sides, which is what separates it from the OSFP-AMP-ZR with its duplex LC line side.

It works with Arista 400ZR transceivers (OSFP-400G-ZR, QDD-400G-ZR) through the CAB-LC8-CS 8-channel passive coupler-splitter cable. The CAB-LC-CS-0.2M patch cable converts the line side to duplex LC dark fibre. It plugs into any Arista QSFP port and is managed through Arista EOS and CloudVision.

Enquire with XS Network Tech for new or used pricing and availability.

Features

- Booster and pre-amp EDFAs integrated into a single QSFP module, removing the need for an external optical line system on DCI links
- Automatic gain control gives plug-and-play operation with no configuration, for links from 2m to 120km
- Supports up to 8 x 400ZR waves (3.2T) per fibre pair with the passive CAB-LC8-CS coupler-splitter
- Configuration, monitoring and telemetry through Arista EOS CLI and CloudVision
- Pre-amp and booster-amp input and output power visibility
- Plugs into any Arista QSFP port
- Functionally identical to OSFP-AMP-ZR, differing only in form factor and optical connectors

FAQs

Q: Does the QSFP-AMP-ZR need a licence or subscription?
A: No licence or subscription is stated for the module. Management and telemetry are native in Arista EOS.

Q: How is power supplied to the module?
A: It draws a maximum of 4 W from the host QSFP port, with a maximum case temperature of 70 C.

Q: What does it work with?
A: It works with Arista 400ZR transceivers (OSFP-400G-ZR, QDD-400G-ZR) via the CAB-LC8-CS 8-channel coupler-splitter cable. The CAB-LC-CS-0.2M patch cable converts the line side to duplex LC dark fibre.

Q: How does it differ from the OSFP-AMP-ZR?
A: It is functionally the same but uses a QSFP form factor with duplex CS connectors on both the line and client sides. The OSFP-AMP-ZR has a duplex LC line side.

Q: How many 400ZR channels can it amplify?
A: It amplifies 1 to 8 x 400ZR channels, up to 3.2T per fibre pair, at 200 GHz channel spacing.
