Description

QSFP-DD optical transceiver providing two independent 100G CWDM4 interfaces from a single port. Uses duplex CS connector and single-mode fiber for up to 2 km reach per 100G channel. Ideal for data center leaf–spine or campus aggregation. Use CS-to-dual-LC patch leads if interfacing with LC panels.

Features

- Consolidates two 100G CWDM4 links in one QSFP-DD slot
- 2 km reach on cost-effective SMF
- Compact CS connector for high-density patching
- Standards-aligned CWDM4 wavelengths for interoperability
- Telemetry via DOM/DDM for simplified operations

FAQs

Q: What cabling do I need to connect to LC panels?
A: Use a CS-to-dual-LC duplex breakout patch cable for each 100G channel.

Q: Is this interoperable with 100G CWDM4 optics on the far end?
A: Yes. Each 100G channel is CWDM4 and interoperates with standard 100G CWDM4 optics within CWDM4 specs.

Q: Does the host port need to support breakout?
A: Yes. The QSFP-DD host must support 2x100G breakout mode.

Q: Can this be used over multimode fiber?
A: No. It is designed for single-mode fiber (SMF).
