What are the primary use cases?

Ideal for data center uplinks, ISP aggregation, edge computing, and high-speed fiber backbone interconnects.

How does it improve network performance?

Delivers low latency (<1 µs), high throughput, QoS enforcement, and reliable optical uplinks for carrier-class applications.

What are the operating environment specifications?

Operating temperature: 0 °C to 50 °C; humidity: 5 % to 95 % non-condensing.

What is the board’s power consumption?

Typical power draw is 8 W under full load.

What warranty and support are included?

Includes a 3-year limited hardware warranty and 24/7 D-Link certified technical support.

How does it integrate with management tools?

Fully manageable via SNMP v1/v2c/v3, CLI, and D-Link Network Management System for unified control.

What security features are available?

Supports link flap detection, port security, ACL enforcement, and encryption pass-through when managed by the chassis controller.

DES-85-2TE-SFP+ Use Case

Hyperscale Data Center Interconnect with DES-85-2TE-SFP+

In a multi-rack data center deployment, IT architects install D-Link DES-85-2TE-SFP+ boards in core switches to provision dual 10 Gigabit optical uplinks per line card. This high-density solution delivers ultra-low latency, 20 Gbps aggregate bandwidth, and hot-swappable SFP+ ports for seamless maintenance. Outcome: scalable spine-leaf fabrics with 50% higher throughput and 30% lower operational complexity compared to legacy 1 Gbps links.

Enterprise Campus Backbone Upgrade to 10G Optical

A global enterprise replaces aging 1 Gbps links between building MCUs and aggregation switches by deploying DES-85-2TE-SFP+ in modular D-Link chassis. Leveraging existing single-mode fiber, the 10 Gigabit optical service board enables plug-and-play SFP+ transceivers and automatic link negotiation. Outcome: 10× faster data transfer for unified communications, video conferencing, and cloud applications with zero downtime and predictable ROI.

Metro Ethernet Service Delivery for SMBs

A regional service provider uses D-Link chassis populated with DES-85-2TE-SFP+ boards to offer dedicated 10 Gbps circuits to small and medium businesses over metro fiber rings. The dual-port SFP+ architecture supports diverse optics and built-in redundancy for SLA-driven uptime. Outcome: new revenue streams through premium 10G Ethernet services, simplified provisioning by hot-swappable modules, and guaranteed 99.99% network availability.
