Description Features Technical Parameter
VT-86XXW series field-type 1310nm optical transmitter is a special optical transmission equipment that can adapt to and meet the field working environment in HFC broadband transmission network. The product adopts direct light intensity modulation, low RF signal input level requirements, good sealing and heat dissipation performance, making the product suitable for a variety of harsh outdoor working environments. In the working frequency band of 860MHz, the transmission capacity is large and the nonlinear distortion is small; automatic optical power control circuit, automatic laser temperature control circuit, laser protection circuit and laser slow start circuit can effectively extend the working life of the laser and ensure the long-term operation The stability of the output optical power at the time.

The pre-distortion circuit enables the product to have excellent non-linear indicators to ensure multi-level cascade and long-distance transmission of the optical fiber network to achieve remote user coverage.

The product has a microprocessor circuit and an embedded VFD for monitoring and displaying all working states and parameters of the optical transmitter. The perfect laser working monitoring and protection circuit makes the product have high stability and high reliability.
