Avago Technologies’ AFCT-57D3ATMZ optical transceiver supports high-speed serial links over single-mode optical fiber at signaling rates up to 8.5 GBd. Compliant with Small Form Pluggable (SFP and SFP Plus) mechanical and electrical specifications for LC Duplex transceivers, ANSI Fibre Channel for FC-PI-4 and FC-PI-2 for gigabit applications. The part is electrically interoperable with SFP conformant devices.
The AFCT-57D3ATMZ supports both TX and RX Rate Select feature. It uses Rate Select to vary maximum transmitted RS(1) optical power for assisting interoperability with legacy 2G and 4G receivers. Fibre Channel FC-PI-4 has
increased maximum received optical powers with each new data rate. As long as minimum link distances are chosen to avoid receiver overload, Rate Select enabled transceivers are not required. However, if link distances vary from 2 m to 10 km, the transmitter Rate Select RS(1) can be utilized to guarantee interoperability with low speed receivers.
The AFCT-57D3ATMZ has isolated signal and chassis SFP grounds to maximize flexibility in host system applications.
As an enhancement to the conventional SFP interface defined in SFF-8074i, the AFCT-57D3ATMZ supports SFF-8472 (digital diagnostic interface for optical transceivers). Using the 2-wire serial interface defined in the SFF-8472 MSA, the AFCT-57D3ATMZ provides real-time temperature, supply voltage, laser bias current, laser average output power and received input power. This information is in addition to conventional SFP base data. The digital diagnostic interface also adds the ability to disable the transmitter (TX_DISABLE), monitor for Transmitter
Faults (TX_FAULT), and monitor for Receiver Loss of Signal (RX_LOS).
