Finisar’s Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM transport with dramatically lower power and cost in a standard pluggable Small Form Factor Pluggable (SFP) package. The FWDM-1629 is designed expressly for service providers deploying DWDM networking equipment in metropolitan Ethernet and SAN networks. The fiber link budget has been enhanced to 30dB with an Avalanche Photo Diode (APD) receiver.

In addition, digital diagnostic features are implemented as described in Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical Transceivers”2.

APPLICATIONS

• Amplified DWDM networks

• Bandwidth aggregation

• Ring topologies with OADM

VI. Wavelength Stabilization

The laser transmitter will not be turned on until its temperature is adjusted to ensure operation within the specified channel (X +/- 0.4nm). This temperature stabilization time is dependent on the ambient temperature conditions, but will typically occur within 90 seconds of powering the device. The device will transmit within the specified wavelength tolerance (X +/- 0.1nm) within 5 seconds of transmitter operation.

IX. Serial Communication Protocol

All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP MSA1. These SFPs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h. For details on interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E2PROM.”4

Finisar’s DWDM SFPs also support extended diagnostic features as described in Finisar Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical Transceivers”2. A controller IC that monitors system parameters such as laser current, module temperature, transmitter power, and received power is accessible at address A2H.
