8/12/24-Fiber MTO/MPO Lookback Module
MTP loopback modules are used widely within testing environment especially within parallel optics 40G networks. Devices allow verification and testing of transceivers featuring MTP interface – 40GBASE-SR4/CSR4 QSFP+ devices. Loopbacks are built to link Transmitter (TX) and Receivers (RX) positions of MTP transceivers interfaces. MTP loopbacks can facilitate and speed up IL testing of optical networks segments by connecting them to MTP trunks/patch leads.

Product Details
| Standard ConnectorMTP loopback connector adopts 8/12/24 fibers with different types of polarity. |  |
 | Upgrade DesignThe fiber loopback is slim and takes up less space than tranditional fiber loopback. |
| Dustproof FunctionEvery loopback module is equipped with a dust cap, which is convenient to protect it from pollution. |  |
SUNMA provides type 1 polarity loopback modules as default for your networks.
And please note that 8/12 fibers MTP is for 40G QSFP+/100G QSFP28, 24 fibers is for 100G CFP/CXP.
Collocated with 40G or 100G MPO/MTP interface transceivers
Loopback module can be used for testing the transmission capability and receiver sensitivity of fiber optic network equipment.
