Introduction
The EZSNET XZS-SFP10G-LR is a 10GBASE-LR Small Form-factor Pluggable Plus (SFP+) optical transceiver designed for 10 Gigabit Ethernet communication over single-mode fibre. Operating at a wavelength of 1310 nm, the module supports transmission distances of up to 10 km using duplex LC fibre connections.
This teardown examines the internal construction of the transceiver, identifies the major electronic and optical components, and investigates how the module implements high-speed optical communication within the standard SFP+ form factor.

Flip the SFP+ Module upside down.
-
Find the 2 clicked in metal tabs on each side and use a small flathead to lever them up and out of the casing.
-
-
-
Gently, without bending, pull the SFP+ module up and away from the jacket so it comes off.
-
Make sure to store it somewhere safe.

Flip the SFP+ module sideways.
-
Gently, using a flathead screwdriver, lever the top casing away from the bottom casing, making sure to not fully remove it.
-
-
-
Carefully flip the SFP+ module back upright.
-
Remove the top casing gently without making the lever mechanism move.
-
-
-
Using a small flathead screwdriver, lever the TOSA/ROSA retainer away from the bottom casing.
-
Take care to store this somewhere safe.
