Laser Transmitter with return path receivers
Single mode 1310nm fibre optic laser transmitter, employing high performance thermally stabilized distributed feedback (DFB) lasers with an integrated optical isolator.
It is designed to transmit AM-VSB, CATV, CCTV, DVB-C and DVB-T signals together with DOCSIS over a 1310 nm single mode optical fiber, RF frequency range is 45Mhz to 1Ghz
The unit incorporates a comprehensive alarm and status monitoring system of all laser operating parameters such as DC laser bias current, laser temperature, cooler current, optical output power, RF levels, and more
PBN (Pacific Broadband Networks) Fibre Optic Laser Transmitter
Model LT1310-10
Market release 2011
Ex large CATV/Communications network within a government facility and removed due to equipment upgrade only - not faulty product
Standard 19" 1RU form
COSMETIC CONDITION:
Excellent - no issues with the casing, display or the front panel control buttons and all ports are fine also.
TESTING:
Not a lot I can do with this equipment, being only part of a fibre system infrastructure.
The overall concept is that you have a signal source, RF range (45Mhz to 1Ghz) and this goes into the input of this equipment. The optical link then provides the baseband at 1310nm along which the RF input signal "rides". I do have a suitable field node receiver, the AMCP1315 advertised separately so with the two units, a very good optical link can be set up.
I have no suitable RF input signal source so my testing is unable to proceed further.
Powers up, boots up and menu can be navigated correctly
Upon boot up, the LCD displays shows
NO URGENT ALARMS
I do have an alarm condition indicated on the front panel leds:
ALARM STATUS - orange
RF/OPTIC STATUS - orange
I then referred to the manual and the LED's status appear to be normal when there are no signal inputs (RF 45Mhz - 1Ghz) - loss of input appears to create an alarm condition
