SFP 1.25Gb/s BIDI 1490nm/1550nm 120km LC DDM SFP Transceiver
Modules
Description
Miray’s SFP-1G-BX120U/D 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 photo-detector. The
module data link up to 120KM 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.
