KLOTZ adds APC connectors to FiberLink series

The KLOTZ FiberLink series, which includes the FiberFlex Ultra cable in single-mode, is now available not only with the standard FC, SC or ST connectors with PC/UPC polish but also with E2000-APC, FC-APC, LC-APC connectors and SC-APC polish.

APC is short for Angled Physical Contact; on these connectors, the ferrule surface is polished with an angle of 8°. As a result, the connector is said to offer improved return loss compared to other PC/UPC polished connectors. Connectors with APC polish must not be paired with connectors with PC/UPC polish – this could lead to very high insertion losses and damage to the connector.

To avoid faulty connections, all KLOTZ APC connectors are available in the typical green colour. PC/UPC connectors are usually blue, which ensures easy differentiation for the user.

APC connectors, with their improved optical performance, are usually used for high-quality and critical connections, especially when increased return loss is crucial, such as in WDM or CWDM systems where up to 16 wavelengths are transmitted over one fibre.

The compact E2000 connector features an automatically closing protective cap. This shields the connector from contamination and also prevents the human eye from being exposed to the laser. The FC connector is characterised by its ceramic ferrules as well as its alignment accuracy and is preferably used for precise and securely lockable connections. Green LC and SC-APC connectors are comparable in handling and size to the conventional blue PC/UPC connectors.


The cable manufacturer has also released the OT234H-D high-quality digital cable for long distances with an FRNC jacket. Based on the OT234H digital cable, the OT234H-D cable fulfils the CPR class Dca – s1, d1, a1 according to EN50575 for the installation sector. It has a particularly low signal attenuation as a result of its 0.34mm² (AWG 22/7) conductor cross-section and low capacitance. This is said to make the cable suitable for extremely long distances and transmits both analogue microphone and line audio signals, as well as digital signals such as AES/EBU and DMX control commands. Two shields protect against noise, while a tinned copper braid facilitates assembly with connectors. The FRNC jacket with an outer diameter of 5.8mm is suitable for a temperature range of –30°C to +70°C. With a minimum bend radius of only 35mm, the OT234H-D is said to be suitable for all installations.
