BKtel expands its portfolio with SCTE-174 conform RFoG equipment

May 19, 2011

The time of non-standardized RFoG equipment which has lead to severe problems with early-to market devices has come to an end in December 2010, with the release of the specification 174 by the Society of Cable and Technology and Engineering (SCTE).  Trading under the name Fiber.DOCSIS BKtel offers now a set of equipment which complies with this first RFoG standard.

The new products include return path receivers, WDM modules, high-power optical amplifiers and two types of RFoG micro nodes, supporting RFoG networks at the headend, in hub sites and at the subscribers’ premises. Using optimised optical design and a unique ultra-low noise receiver technology Fiber.DOCSIS provides an extraordinary high optical budget of 28 dB enabling high splitting ratios or extended reach applications.

The BOR4085 quadruple return receiver is the key element in the system. The device has an exceptional low noise current of 0.8 pA/sqrt Hz. The four receivers units can be used separately or combined internally with an equivalent noise performance of a single discrete receiver. It comes in BK style housing and allows a compact and low power consumption solution for indoor and outdoor applications.

The RFoG micro fiber nodes XON40.BFN and XON45.BFN offer excellent downstream performance in a low and a high output level version and a SCTE-standard complying burst mode operation for the upstream. The node XON50.BFN provides an additional fiber management for easy installation in buildings.

BKtel is involved in the standardization and will continue to work in IEC for the further extension including the standardization of management functions. The company is active part of TC209 within CENELEC being technically responsible for HFC/FTTx standardization documents and has proposed IEC RFoG standardisation and is about to prepare first draft documents to be discussed (including system aspects, node management and RFoG device performance).
