Overview
The AFCT-570 Z 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-570 Z 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-570 Z 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.
