WTD · Optical Transceivers & SFP
6G SFP+ 850nm transceiver (WTD-coded stock)
The single item we carry under the "WTD" stock tag is a 6G-class SFP+ transceiver, 850nm, rated to 300m over multimode fiber. We have not been able to independently verify "WTD" as an established, distinct telecom optics manufacturer, and we are not going to invent a company history for it. The item's description in our stock record carries a "NOK" prefix, which may indicate that this is Nokia-compatible or Nokia-coded stock rather than a product of a separate brand called WTD — but we cannot confirm that from the record alone, so we are stating it as a possibility, not a fact. What we can state factually is the part's technical profile as recorded: a 6Gbit/s-class SFP+, 850nm wavelength, 300m reach.
How to read these part numbers
Read this listing as a technical description, not a confirmed manufacturer profile: SFP+ form factor, approximately 6Gbit/s signalling rate, 850nm wavelength (multimode-fiber range), 300m maximum reach. We will disclose everything we know about brand, origin and any Nokia-related coding on the quotation and encourage buyers to confirm compatibility with their own host platform before ordering.

Ordering notes
Because brand identity for this item is unconfirmed, we recommend buyers independently verify host-platform compatibility (vendor coding/locking) before ordering rather than relying on the "WTD" or "NOK" labelling alone. Condition is stated per quotation as refurbished or used-tested. CRS PLUS is an independent broker and does not claim any manufacturer authorisation for this item. Hardware only. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.
Lifecycle and availability
We do not have independently verifiable information about a lifecycle, production status or corporate history for "WTD" as a brand. The part is supplied as refurbished or used-tested stock, with full record detail and condition confirmed per quotation.
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
We record it as the manufacturer tag on this stock item, but we have not been able to independently verify WTD as an established, distinct telecom optics manufacturer. We are disclosing that honestly rather than presenting an invented company background.
