Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Access, Terminals, Transmission and Multiplexing (ATTM). Introduction An Optical External Network Testing Interface (ENTI) is a passive element t
16、hat sits at the boundary between the Access Network (AN) and the end user (subscribers) in-house FITH Network. From a certain point of view ENTI can be regarded as a testing demarcation point between the access network and the wiring at the customer premises. External Network Testing Interface ENTI
17、defines the point for testing the operators network while isolated from the customers home wiring. ETSI ETSI TS 102 873 V1.1.1 (2010-10)51 Scope The present document defines the functional and technical characteristics applicable to the Optical External Network Testing Interface (ENTI) terminated wi
18、th Singlemode fibre which provides testing capability at the demarcation point between the line of the FTTH operators network and the customers cabling inside the house. The present document describes optical ENTI for new homes. An optical ENTI is positioned in a distribution space. It is connected
19、to an ONT by an optical terminated cord. The home cabling is not considered in the present document. The present document specifies the functional characteristics and performance requirements for the optical ENTI within the subscriber premises and for the needs of the FTTH optical access network. 2

43、stics Optical ENTI is the physical point at which a subscriber is provided with access to an optical communications network. An ENTI device will be installed for each subscriber. Optical ENTI unit is enclosed in a durable housing appropriate for use in a distribution space and constitutes integral p
44、art of the subscriber line of the operators network. The ENTI: is a part of the demarcation point; is a measuring and testing point; will allow isolation of customers in-house cabling from the operators network; ETSI ETSI TS 102 873 V1.1.1 (2010-10)8 will encompass laser safety; will allow optical c
45、onnectivity. Additional functional characteristics of the ENTI are: fibre management system within housing (tray, splice holder, etc.); fibre overlength for consecutive splicing as well as management of fibre overlengths. 4.1 Optical ENTI location ENTI, as it is described in the present document for
46、 new homes, must be located inside a distribution space (collocated near the home distributor as depicted in figure 1). Optical ENTI characteristics for use outside a distribution space in existing homes are not considered in the present document. Figure 1: Optical ENTI within a distribution space 4
47、.2 Optical termination Optical termination is accomplished by means of fibre optic connector plug and adaptor. The termination of the fibre is a connector plug. The connector plug can be pre-terminated (pre-terminated cable) at the manufacturers plant or by means of field mountable connector system.
48、 Connector plug is positioned in the adaptor. Adaptor is a part of the optical ENTI outlet and it is an integral part of the optical termination. Optical termination has two connection functions: connection to the ONT; connection to the measuring equipment. By plugging another connector into the ada
49、ptor optical connection interface is accomplished. ETSI ETSI TS 102 873 V1.1.1 (2010-10)9The requirements on optical connection interface are: mechanical; optical. The mechanical requirements shall be according to CENELEC EN 61754 14 series and optical performance according to CENELEC EN 61755 15 series. Optical connectors may be PC or APC (type SC, LC, LX.5 etc.) 4.2.1 Pre-terminated connectors with pigtails Pre-terminated connector with pigtail is a product configuration cons
