Fibre Optic products

 

Ananya has partnered with Bee Pitron, Russia for Fibre Optics Products. Fibre Optic products offered are Rotating Optical connector (ROC), Optical Splitter, Optoelectronic Transmitter/ receiver and Radiation-stable ultra thin glass plates.

Rotating Optical Connector (Roc):

G.657 ITU-T ISO/ IEC 11801 IP68

ROC is worked out on the basis of two opposed lens optic contacts (LOC).The design of the case allows rotation of ball bearings. For ROC installation standard fasteners are used. In ROC design, a special armour-clad optical fibre cable is applied. The ROC case design provides for hermetic mating of static and rotating elements. ROC is manufactured from high quality imported materials, 99% of its weight being metal elements with protective coating. All the non-metallic details are manufactured from synthetic polymer materials. ROC is completely resistant to sunlight, mould, pollutants and electromagnetic radiation.

ROC provides for data stream transmission with the following optical parameters

Operating wavelength: 1310 to 1680 nm
Injection loss: no more than 4 dB
Reflection loss: not less than 40 dB
Data steam transmission rate: 100 Gbps

ROC has the following calculated characteristics of reliability and durability

Operating temperature: -65°Ϲ to 150°Ϲ
Rotation speed [-30°Ϲ to 110°Ϲ]: 5000 rpm
Length: no more than 650 mm
Outer diameter: no more than 46 mm
Weight: no more than 0.4 kg
Reliability function within a predetermined range: 0.97
Mean time between failures [MTBF]: 390000 hours
Useful lifetime: 20 years

Optical Splitter 1:20:

G.657 ITU-T ISO/ IEC 11801 IP68

OS is intended for integration into the onboard cable network (OCN) of special-purpose equipment in compliance with GOST/ Russian national standard/ to link equipment units. It provides for division or summation of data streams from the single input ports to 20 output ports. OS is connected with the OCN via FC/ UPC connectors.

OS is worked out in a hermetical metal case with built-in pigtail ports. It is manufactured from high quality imported materials with 90% of its weight being metal components all having protective coating. All the non-metallic elements are manufactured from synthetic polymeric materials. OS is completely resistant to sunlight, mould, pollutants and electromagnetic radiation.

OS provides for data stream transmission via the optical fiber of 9/125 µm type with the following optical parameters

Operating wavelength: 1310 to 1650 nm
Injection loss: no more than 16 dB
Reflection loss: not less than 40 dB
Data steam transmission rate: more than 100 Gbps
Port pigtail length: any (typical 500 mm)

OS provides for data stream transmission under the following conditions

Operating temperature: -50°Ϲ to 85°Ϲ
Overall dimensions of the case: 100x50x12 mm
Weight: no more than 0.19 kg


OS has the following calculated characteristics of reliability and durability

Reliability function within a predetermined range: 0.997
Mean time between failures [MTBF]: 2700000 hour
Useful lifetime: no less than 15 years

Optoelectronic Transmitter/ Receiver:

G.657 ITU-T ISO/ IEC 11801 OC24

OET/ OER modules provide simplex conversation of data signal. OET converts signal from electric to optic transfer media and OER coverts data from fibre optic data lines.

OET/ OER modules are intended for development of media converters.

OET/ OER modules are completely resistant to solar radiation, aggressive pollutants and fungal growth.

OET/ OER modules work with single mode optical fiber of 9/125 µm type with the following optical parameters

Operating wavelength: 1310/ 1550 nm

Current consumption: no more than 100 mA
Output capability (OET): no less than -1 dB
Receiving sensitivity (OER): not less than -23 dB
Data stream transmission rate: 1.25/ 2.5 Gbps
Port pigtail length: any (typical 500 mm)

OET/OER modules operate under the following conditions

Operating temperature: -60°Ϲ to 80°Ϲ
Overall dimensions of the case: 80X50X10 mm
Weight: no more than 0.019 kg

OET/ OER has the following calculated characteristics of reliability and durability

Reliability function within a predetermined range: 0.998
Mean time between failures (MTBF): 430000/ 640000 hours
Lifetime: no less than 12 years
