1. 

FIBER OPTIC DOWNSTREAM RECEIVER 

a. 

Measure optical power at input to receiver 
1.)  If optical power > -1 dBm, add an optical attenuator until optical level is 

between -8 to -1 dBm (optimum = -4 dBm). 

2.)  If optical power < -8 dBm, performance will be degraded.  Check fiber 

optic jumpers, ensuring the connectors are clean. 

b. 

Clean optical connector per maintenance instructions. (See section E.) 

c. 

Verify correct optical connector is being used (SC/APC is standard on the 
UMFN) 

d. 

Insert optical connector into socket labeled “

OPTIC IN

”.

.

 

2. RF 

CABLE 

a. 

Install type F-male connectorized RF coaxial cable to “

RF OUT

” port. 

3. POWERING 

a. 

Verify AC voltage rating on the included power adapter is correct for the 

available power source. 

b. 

Connect F-male connectorized RF coaxial cable to the power adaptor and 
the “

POWER IN

” port. 

c. 

(Optional) In case of reverse powering through the RF port: 
1.)  Connect an F-male connectorized RF coaxial cable between 

RF OUT

” port on the Mini Fiber Node and the port labeled “

TO AMP

” 

on the power inserter (MPI -1G). 

2.)  Connect the F-male connectorized RF coaxial cable to the power 

adaptor and the port labeled “

DC IN

” on the power inserter. 

3.)  Connect F-male connectorized RF coaxial cable from “

TO TV

” port on 

the power inserter to network. 

d. 

Connect the power adaptor to AC voltage source. 

 

4. POWERING 

ON 

a. 

Check for power light on the Mini Fiber Node, i.e. green LED indicator next 
to the “

POWER IN

” port.  

5. RF 

OUTPUT 

LEVEL 

a. 

Verify RF output level with a spectrum analyzer or RF field strength meter. 

NOTE: 

If powering through an optional power inserter (MPI-1G), check 
the RF output level at the “

TO TV

” port of the power inserter. 

NOTE: 

Typical levels will be +27 dBmV with –4 dBm optical input to the 

OPTIC IN

” port. 

E .   M A I N T E N A N C E  

 

DANGER:  AVOID DIRECT EXPOSURE TO THE LASER BEAM. 

Invisible radiation continues when open or when operating with fiber optic cable disconnected. 
Never operate unit with a broken fiber or with fiber connector disconnected. 

1. 

Use a lint-free cloth (3 x 3 cm recommended). 

2.  Moisten one-half of the cloth with >90% pure ethyl alcohol. Gently wipe the 

connector end face. 

3. 

Using the dry half of the cloth, wipe the connector face and rapidly shake the 
connector. 

4. 

Before fastening the connector, ensure it is completely dry. 

 

CAUTION:  To prevent dust-particle abrasion

, do NOT spray compressed air 

directly onto the connector’s end face. 

 

To avoid eye injury

, never look directly into the connector’s end face.
