Ether-Loop is a battery GbE loopback device that can operate over optical/electrical
SFP and RJ45 interfaces. Pairs with ALBEDO testers or any compatible device. It
is and probably the most cost-effective solution to test end-to-end SLAs.

All you need in an battery operated Loop-back

Ether.Loop is an Ethernet loop-back reflector, flexible and low cost. It has both a electrical RJ-45 and optical SFP interfaces. Ether.Loop provides Ethernet loop back for all levels of service testing and monitoring in a compact, battery operated unit that can manage Ethernet frames, IP and TCP/UDP (Layer 1 to 4) at wirespeed operation.

Every Ethernet frame / IP packet received is inspected and the following parameters are automatically swapped and returned including Source/Destination MAC, IP address, and TCP/UDP ports. It is lightweight, rugged design protected with rubber boot, and can operate either with ALBEDO Ether.XX family of tester or any of the industry test and measurements devices.
