Overview

The AFCT-570xZ family is compliant with both IEEE

802.3Z (1000BASE-LX) and Fibre Channel 100-SM-LC-L.

It also complies with the SFP Multi-Source Agreement

(MSA) specification. These transceivers are intended for

premise, public and access networking applications.

They are qualified in accordance with GR-468-CORE,

and transmit data over single-mode (SM) fiber for a link

distance of 10 km, in excess of the standard.

The AFCT-5705Z family of optical transceivers adds

digital diagnostic monitoring to standard SFP function-

ality, enabling fault isolation, components monitoring

and failure prediction capabilities.

General Features

The AFCT-570xZ is compliant to 1 GbE and 1G FC speci-

fications.

This includes specifications for the signal

coding, optical fiber and connector types, optical and

electrical transmitter characteristics, optical and elec-

trical receiver characteristics, jitter characteristics, and

compliance testing methodology for the aforemen-

tioned.

This transceiver is capable of implementing both Single

Mode (SM) and Multimode (MM) optical fiber applica-

tions in that order of precedence in the event of con-

flicting specifications. In addition, the SM link type

exceeds the 2 m to 5 km 1000BASE-LX specification by

achieving compliance over 2 m to 10 km. The MM link

type is expected to meet the 62.5 μm MMF specification

when used with an “offset launch” fiber.

SFP MSA Compliance

The product package is compliant with the SFP MSA with

the LC connector option. The SFP MSA includes specifica-

tions for mechanical packaging and performance as well

as dc, ac and control signal timing and performance.

The power supply is 3.3 V dc.

The High Speed I/O (HSIO) signal interface is a Low

Voltage Differential type. It is ac coupled and terminated

internally to the module. The internal termination is a

100 Ohm differential load.

Installation

The AFCT-570xZ can be installed in or removed from

any MSA-compliant Pluggable Small Form Factor (SFP)

port regardless of whether the host equipment is oper-

ating or not. The module is simply inserted, electrical-

interface first, under finger-pressure. Controlled hot-

plugging is ensured by 3-stage pin sequencing at the

electrical interface. This printed circuit board card-edge

connector is depicted in Figure 2.

As the module is inserted, first contact is made by the

housing ground shield, discharging any potentially

component-damaging static electricity. Ground pins

engage next and are followed by Tx and Rx power sup-

plies. Finally, signal lines are connected. Pin functions

and sequencing are listed in Table 2.
