Fiber to the home (FTTH) is the ultimate development goal of broadband access, and the TLMOR21039/2D mini optical receiver is the end product to meet this goal.
This fiber optic receiver adopts low-power light-receiving technology to meet the needs of FTTH fiber-to-the-home CATV reception. The machine is also equipped with an optical power receiving and monitoring normal LED indicator on the panel for user convenience. "D" is a filter type optical receiver.

Power Supply/ Consumption
1 Power Input: TLMOR210392/D is the external power supply input port, First should be the DC+5V external voltage stabilizer output line connected to the machine POWER IN, then put DC+5V external mano-stat insert 100/240 V, DC5V Face posted power light, show Power part is regular work.
2 Optical Input: This fiber optic product is the input interface of the optical signal, In optical access, should be clean APC TOP use alcohol then align adapter sunken mouth, fibre mouth march link; When light signal access, face OPTICAL（≥-15dBm）light, show Power part is regular work; TLMOR21039/2D receive 1550nm wavelength optical signal only.
3 RF Output Level Adjustment: TLMOR21039/2D is the RF output port, please use level table testing before using if possible. the level also down, means optical signal 1dB, RF2dB. it is RF Output level decay, quantity has transferred to the minimum. When the output level and the design requirements have any deviation, Can adjust the attenuation amount, with the design requirements.
1. This machine is an indoor structure and should not be used in places that are easily invaded by rainwater; it should have proper space in the indoor box to facilitate heat dissipation; the shielding net of the output cable must be grounded, and the grounding resistance should be less than 4Ω.
2. The pigtail input and cable output must be reserved for a certain length to avoid accidents. If the optical interface is not used, please do not remove the seal. The machine by TUOLIMA is equipped with: SC/APC. When connecting, it is better to use the same specification. Connector, do not use different types of joints.
3. The local RF output is directly connected to the user branch or distributor. The branch and distributor output null terminals must be connected with a 75Ω dummy load. Otherwise, the set-top box will cause mosaic due to the input impedance
