Frequently Asked Questions
What is 100GBase-DWDM and why does it matter?
100GBase-DWDM (100 Gigabit Base Dense Wavelength Division Multiplexing) enables multiple 100Gbps data streams over a single fiber by using different wavelengths. This QSFP28 transceiver uses PAM4 modulation to achieve 100Gbps throughput efficiently, making it ideal for high-capacity, long-distance network links without requiring additional fiber infrastructure.
Is this transceiver compatible with Cisco equipment?
Yes, the AddOn QSFP-100G-2DW31-S-AO is fully compatible with Cisco QSFP-100G-2DW31-S specifications. It integrates seamlessly into Cisco data center switches, routers, and optical networking platforms that support 100GBase-DWDM modules, providing a cost-effective alternative to OEM transceivers.
How far can this 100GBase-DWDM transceiver transmit?
This module supports transmission distances up to 80km over single-mode fiber at its 1552.52nm wavelength. This extended reach makes it suitable for metro and long-haul applications, connecting data centers across cities or large campus networks without signal regeneration.
What does TAA compliance mean for procurement?
TAA (Trade Agreements Act) compliance ensures this QSFP28 transceiver meets U.S. federal procurement standards and can be purchased by government agencies and regulated organizations. It guarantees the product meets specific country-of-origin and manufacturing requirements for sensitive environments.
