| LC connector: (Lucent Connector or also Local Connector) The LC connector was developed by Lucent Technologies. Due to the compactness (Small Form Factor) it features a high port density and is therefure used in switches quite often. LC connectors are available in two common formats: - LC-PC / LC-UPC (PC = Physical Contact, UPC = Ultra Physical Contact)
- Is also labeled "grade grind"
- UPC is an extension of PC and features better attenuation
- LC-PC / LC-UPC connectors are usually blue
- LANCOM Systems SFP modules only use LC-PC / LC-UPC connectors
- LC-APC (APC = Angled Physical Contact)
- Is also labeled "bevelled grind"
- LC-APC has a grind of 8 degrees
- LC-APC connectors are usually green
Important: LC-PC / LC-UPC and LC-APC must not be connected to each other, as this would lead to an increased attenuation and the connection would most likely not function! |
| MPO/MTP connector: (Multipath Push-On and also Multiple-Fibre Push-On) / (Mechanical Transfer Push-On) The MPO connector was originally developed by NTT and further developed to MTP by the joint venture USA-Conec. - Compared to MPO, MTP features mechanical and optical advantages, e.g. a detachable connector housing. An MTP connector is always also an MPO connector.
- MPO/MTP contains up to 72 fiber strands (max. 12 strands per row with a maximum of 6 rows) and therfore therefore features very high data transfer rates. For 40 GBit/Sec. usually cables with 12 fiber strands are used (8 strands necessaryerforderlichnecessary) und für and for 100 GBit/SekSec. Kabel mit 24 Fasern cables with 24 strands are used (20 Fasern erforderlichstrands necessary).
