The DES-85-2TE-SFP+E is a 2-port 10 Gigabit SFP+ enhanced optical service board designed for D-Link switches to add high-speed fiber connectivity.
This SFP+ board is compatible with select D-Link chassis switches that feature an expansion slot, including models in the DES-3600 and DGS-3630 series.
The board supports all industry-standard 10GBASE-SR, 10GBASE-LR, 10GBASE-ER and CWDM/DWDM SFP+ transceivers for multimode and single-mode fiber.
Power down the switch, insert the board into an available expansion slot, secure the captive screws, then power on the switch to auto-detect the module.
No. The DES-85-2TE-SFP+E requires switch power-off during insertion or removal to ensure proper initialization and avoid hardware damage.
Using 10GBASE-ER transceivers over single-mode fiber, the board supports links up to 40 km.
Yes. When paired with compatible SFP+ transceivers and fiber cabling, it enables high-speed stacking and uplinks between D-Link chassis switches.
The DES-85-2TE-SFP+E consumes a maximum of 5 W under full load, as specified in the product datasheet.
Yes. The switch’s firmware supports Link Aggregation Control Protocol (LACP) for active-active redundancy over the two SFP+ ports.
Operating temperature range is 0 °C to 50 °C, with relative humidity from 10 % to 90 % non-condensing.
Visit the D-Link support website, enter SKU DES-85-2TE-SFP+E, and download the firmware under the “Software & Driver” section.
The board is backed by D-Link’s limited lifetime warranty, conditional upon registration and proof of purchase.
Check the front-panel LEDs: a solid green LED indicates a valid 10 Gbps link; blinking green means traffic activity.
Yes. You can install both enhanced and standard SFP+ boards in different slots, but adhere to the chassis’ slot population guidelines.
Periodically inspect fiber connectors for dust and clean with recommended fiber cleaning tools to maintain optimal performance.
The enhanced edition offers extended temperature tolerance, lower jitter performance and improved EMI shielding for demanding environments.
