HH-GZFDN-1.2G  Optical Node

-1310nm and 1550nm double operation way
-Middle-sized aluminum cast housing, perfect waterproof and heat dissipation performance.Adopt international advanced polishing and passivation technics, to made the surface shaped the dense protect coat, it have good performance at heat dissipation, electric conduction and anticorrosive(usually domestic housing are adopt spray paint or spray plastic, heat dissipation is lower at 15%).
-4-way high output independently, can reach 110dBμV, ajustable output level. With high output level and low distortion.
-Install network management responder, provide perfect intellect net function.
-Built-in made from module, convenient to conserve and update,
-Redundancy record, optical receiver, return optical transmitter,  switching supply power are main and backup to switched automaticly.
-4-way independent or single way equal ,so that adjust different transmit distance
-Use insert install of attenuation and insert fixed EQ.
-Use GaAs hybrids
 -Return transmitter parts use FP or DFB laser.
 -Dimensions(mm): 280(L) X 215(W) X 160(H)
