Description
ETU-LINK’s
ESCXX42-3LCD40 Small Form Factor Pluggable (SFP) transceivers are compatible
with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The
transceiver consists of five sections: the LD driver, the limiting amplifier,
the digital diagnostic monitor, the DFB laser and the APD .The module data link
up to 40KM in 9/125um single mode fiber.
The optical output can be disabled by a TTL logic high-level input of Tx
Disable, and the system also can disable the module via I2C. Tx Fault is
provided to indicate that degradation of the laser. Loss of signal (LOS) output
is provided to indicate the loss of an input optical signal of receiver or the
link status with partner. The system can also get the LOS (or Link)/Disable/Fault
information via I2C register access.
