What an alternate must still prove
Single-mode identification versus multimode identification
A single-mode crew can argue that a remote without a 1310 nm or 1550 nm note will be useless on an outside-plant span. A multimode crew can argue that an 850 nm remote with an LC or SC face is the part that matches a short building run. Both arguments depend on the plant already written in the brief. Shipping the other remote because it was in stock at the factory is a deviation, and the quote should label it that way.
New identifier versus refurbished identifier
New stock can make the ID legend readable and the battery door current. Refurbished stock can be the route when the host tester is itself out of production, if the seller states scratched housings, weak tone, and whether a function check against the named host was done. This desk does not perform that check.
Three limits belong on the handoff. A remote does not measure data rate, channel width, or MIMO. It does not carry an impedance or VSWR figure unless the part is actually an RF accessory misnamed in the email. FCC or NRTL paperwork is requested when the host is an active instrument; a passive identifier may have neither, and the supplier should say which case applies. Connector mating cycle, if the datasheet states a count, stays on the adapter line.
Related inquiry names are on the product list. The IEEE 802 overview and ITU-T fiber texts can help name the plant. They are not remote test reports.
