Connecting Ethernet cable
Step 3
Connect the other end of RJ45 connector of the Ethernet cable to the peer device. Based on
the type of the peer device, choose a straight-through cable or a crossover cable.
5.4 Connecting optical fibers
Do not look directly at the fiber optic connector connected with laser. Otherwise, it
may injure the eyes.
Pay attention to the following matters when connecting optical fibers:
Do not stretch or bend the optical fiber excessively. The curvature radius should
be equal to or more than 40mm.
In the chassis, the tail fiber is routed according to the location of components.
Retain a certain margin of fibers when connecting fibers in the cabinet, and put
away the extra tail fiber.
The interface Tx and Rx ends should be connected correctly.
Ensure that the optical connector is clean and cover it with a dust cap after use.
Bind single-core tail fibers with a hook-and-loop strap.
Do not bind the fiber too tight so as not to affect the transmission quality of signals.
To reduce the radiation injury, you must choose Class 1 optical modules when
connecting optical fibers.
Use dustless stick swabs to clean the SFP optical interface before connecting the
fiber.
Use fiber wiper box to clean the fiber connector so as to ensure the strict
requirements of EPON system on optical power.
Connect optical fibers as below:
Step 1
Insert the SFP optical module into the optical interface on the device, as shown in Figure 5-5.
