Can a 10G SFP work in a 1Gb port？
No, a 10G SFP (Small Form-factor Pluggable) module is designed to operate at 10 Gigabits per second (Gbps) and is not compatible with a 1 Gigabit per second (Gb) port.

Can a 10G SFP Run at 1G?
In general, the answer is no—10G SFP modules are not designed to automatically run at 1G speeds. There exist recent developments where Network Equipment Manufacturers (NEMs) have
Can You Connect SFP 1G to a 10G Port? Understanding SFP
The speed limitation for the G1 port is set at 1 Gbps, while the 10G port can reach speeds of up to 10 Gbps. Moreover, devices in this category are usually intended for SFP+ networks,

If the speed on the switch is set to 10-Gbps or auto, the switch advertises all the speeds. If the speed on the switch is set to 1-Gbps, the switch advertises 1-Gbps and 100-Mbps.
Is SFP Compatible with SFP+? Can 10G SFP+ Run at 1G SFP Gigabit Switch
From a practical operations standpoint, it is not recommended to use 10G SFP+ modules in 1G SFP gigabit switch ports. If the network requires 10Gbps performance, it is advisable to adopt switches
Understanding SFP to SFP+ Compatibility: A Comprehensive Guide
Since most SFP and SFP+ transceivers operate at their rated speed, a 10Gb SFP+ optic on a 10Gb switch cannot auto-negotiate down to 1Gb if the other end is a gigabit switch.
Is SFP Port Compatible With SFP+? Can 10G SFP+ Run at 1G Gigabit Switch?
Despite the similarity in shape and size between SFP and SFP+ optical modules, attempting to insert a 10G optical module into an SFP port will not result in a 10G link rate. Instead,
10 Gigabit Ethernet
A single point-to-point link can have different MSA pluggable formats on either end (e.g. XPAK and SFP+) as long as the 10GbE optical or copper port type (e.g. 10GBASE-SR) supported by the

Most SFP and SFP+ transceivers only run at its rated speed as they are manufactured, thus 10Gb SFP+ optics on 10Gb switch can not auto-negotiate down to 1Gb if the other end is gigabit
Can I Use a 10G SFP+ in a 1G Port?
Yes, you can use a 10G SFP+ transceiver in a 1G port, but several factors must be considered. Ensure that your switch, network interface card, or router supports using a 10G SFP+
