Pre-owned, used and refurbished Cisco NM-1A-OC3MM

Supported on the Cisco 3600 series routers and the Cisco 3725 routers, a new or used NM-1A-OC3MM provides a multimode (MM) fiber uplink port. The OC-3 (Optical Carrier level 3) network modules, like a new or pre-owned NM-1A-OC3MM, are available from us for less. We carry a wide selection of new and used Cisco 3600 series routers and accessories, like refurbished and new surplus NM-1A-OC3MM network modules. If you need it quickly, we can help!

Purchase new, refurbished, and used Cisco router equipment at the industry's best prices, including the NM-1A-OC3MM. MULTI-LINK (MLCP) carries a wide variety of Cisco router equipment across all product series. We can provide everything from SOHO to core router requirements.

Our extensive NM-1A-OC3MM inventory allows for quick order turn-around, and we often ship "same day" or within 1-2 business days. What's more? As an independent supplier, we can offer more equipment options than you’ll find from the distributor, including new, used and refurbished NM-1A-OC3MM. In some instances, our pre-owned equipment may still be in new condition and still sealed in original factory packaging, but cost only a fraction of what you would pay for the same product from the distributor.

At MLCP, we guarantee any pre-owned Cisco NM-1A-OC3MM purchase with our comprehensive lifetime warranty. All refurbished NM-1A-OC3MM equipment is tested to factory specifications and transported safely to your door. Our experience as a supplier of used network hardware has taught us that we have to be better than the manufacturer, and that key principle guides us every day.
