Fusion Splice-On Connector
The fusion splice-on connector is field installable and provides easy quick, reliable, permanent field terminations, complying with international standards, such as IEC 61300 series, and Telcordia GR-326-CORE/GR-1081-CORE. It provides more stable quality and performance than that of mechanical field installable types of connectors. Its fiber and field fiber from drop/patchcord cable can be aligned and spliced by using fusion splicers to terminate any types of fibers in the optical cable. The splice point is protected with heat shrink protection sleeve and located in the connector body. It allows installers to reduce service delivery/operation and maintenance time. The fusion splice-on connector (FSOC) is quick, easy and reliable solution for the last mile of FTTH (Fiber to the Home) and data center area. As it is field installable, it eliminates excess cable length and because of fusion splicing, there is no need of field mountable connector which requires high precision skills.
The fusion splice-on connector has many types such as SC, LC, ST and FC, consisting of ferrule assembly, protected fiber stub of defined length, housing, stop ring, protection sleeve, boot and so on.
The typical loss of the physical contact mated in the adapter can be 0.1 dB. Fusion splicing attenuation is typically 0.02 dB, and maximum is 0.05 dB. Therefore total expected loss is in the range of 0.12 dB to 0.15 dB. Expected return loss is over 55dB (UPC) and over 60dB (APC) respectively. It can be adapted to analog networks (≥55dB) with no signal interference and no noise. Types of the alignment methods are IPAAS Core, Fixed V-groove and Active clad. Most importantly, fiber angles and cleaved fiber ends can be seen on the fusion splicer while splicing and the splicing point can be protected with heat shrinkable tubes.
