Ciena 6500 Packet-Optical Platform cards, shelves and pluggable optics

Ciena is an independent optical networking vendor whose 6500 Packet-Optical Platform is one of the most widely deployed DWDM/OTN chassis families in carrier and enterprise networks, and the stock we handle most often is exactly that: 14-slot shelf assemblies, shelf processor and power cards, OTN Flex MOTR transponder/muxponder circuit packs, and the SFP, XFP and QSFP28 optics that populate them. We also carry Ciena's 3920 Service Delivery Switch, a standalone Carrier Ethernet demarcation device that is a separate product line from the 6500 chassis. A number of the pluggable transceivers in our stock carry NTTP-prefixed part numbers, a numbering scheme inherited from Nortel's optical and Carrier Ethernet business, which Ciena acquired in 2010 and which remains compatible with Ciena's own optical platforms.

How to read these part numbers

NTK-prefixed part numbers are 6500 chassis-level hardware: shelf assemblies (e.g. the 14-slot NTK503SA), shelf processor (SP-2), power input, maintenance interface and access-panel cards, and mechanical accessories such as rack kits, installation kits and power lug hardware — these are specific to the 6500 shelf they were ordered for and are not interchangeable across unrelated platforms. NTK532-series OTN Flex MOTR cards are multi-rate transponder/muxponder line cards for the 6500 shelf, distinguished by their port mix (e.g. 1x XFP/8x SFP). NTTP-prefixed items are SFP-class pluggable optics inherited from Nortel's numbering scheme; confirm the exact reach class (IR-1, SR-1, etc.) and wavelength against your shelf slot requirement before ordering. The 170-3920-901 line is the 3920 Service Delivery Switch, a standalone unit rather than a 6500 line card.

Ordering notes

Give the exact part number where you have it — 6500 shelf, controller, power and transponder cards are specific to hardware revision and are not universally interchangeable across shelf generations. For pluggable optics (SFP/XFP/QSFP28), confirm reach class, wavelength and lane configuration against the slot you are filling. Condition is stated per quotation — new, new-surplus or refurbished — and all stock referenced on this page is refurbished/used and sold on that basis; where a destination does not admit used network equipment we will say so and quote accordingly. Hardware only: software licensing and entitlements remain between the buyer and Ciena. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will flag this on the quotation.

Lifecycle and availability

Ciena continues to operate as an independent, publicly traded optical networking vendor, and the 6500 Packet-Optical Platform remains part of its current portfolio. Individual part numbers in our stock vary in age — some 6500 line cards and pluggable optics are still current-catalogue items, while others (including the 3920 Service Delivery Switch, which has reached end-of-sale) are older-generation stock. All items listed here are refurbished/used (condition REF), sourced from the secondary market rather than supplied new. Several transceiver part numbers carry the NTTP-prefix numbering scheme inherited from Nortel Networks' optical networking and Carrier Ethernet business, which Ciena acquired for approximately US$769 million in a deal that closed in March 2010 after Nortel's 2009 bankruptcy filing.

Equipment condition

New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised distributor, with full manufacturer warranty.

New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.

Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.

Condition is confirmed in writing on every quotation before you commit to an order.

Warranty

Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.

Where equipment is supplied new through an authorised channel, the manufacturer's warranty applies and is passed to you.

Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.

Frequently asked questions

Yes. The 6500 family remains part of Ciena's current portfolio, though specific shelf variants, cards and part numbers age out of new-build availability over time. We can tell you whether a given part number is still orderable new or is supplied refurbished.
