The SPS-73180WG series single mode transceivers is small
form factor pluggable module for bi-directional serial
optical data communications such as Gigabit Ethernet
1000BASE-ZX and Fiber Channel 1x SM-LC-L FC-PI. It is
with the SFP 20-pin connector to allow hot plug capability.
Digital diagnostic functions are available via an I2C. This
module is designed for single mode fiber and operates at a
nominal wavelength of 1550 nm. A guaranteed minimum
optical link budget of 39 dB is offered which can
correspond to a link distance of over 180 km (assuming
worst case fiber loss of 0.2 dB/km). The transmitter section
uses a multiple quantum well 1550 nm DFB laser and is a
class 1 laser compliant according to International Safety
Standard IEC-60825. The receiver section uses an
integrated InGaAs Avalanche photodetector preamplifier
mounted in an optical header and a limiting post-amplifier
IC.

4. Measured at 2 7-1 PRBS at BER 1E-12. Receiver sensitivity is better than -36dBm at1.25 Gbps. However, due to the resolution limitation
of Digital Diagnostic Monitoring, the effect readout range for the RX received power at EEPROM A2 is from -10 to -34 dBm.
5. Open collector compatible, 4.7K to 10K ohm pull-up to Vcc (Host Supply Voltage).

protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, MOD-DEF(1:2) appear as no connector
(NC) and MOD-DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the
2-wire serial CMOS E 2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
