Product Description
Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of four sections: the LD driver, the limiting amplifier, the 850nm VCSEL laser, and the PIN photo-detector. The module data link up to 550m in 50/125um multi-mode fiber.
The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate the degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of the receiver or the link status with the partner.
