Frequent plugging and unplugging of fiber-optic cable into and out of optical
instruments can cause damage to the instruments that is expensive to repair. Instead,
attach a short fiber extension to the optical equipment. Any wear and tear due to
frequent plugging and unplugging is then absorbed by the short fiber extension, which
is easy and inexpensive to replace.
•
Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the
canal of the transceiver or cable connector could cause loss of light, reducing signal
power and possibly causing intermittent problems with the optical connection.
•
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS
Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for
the cleaning kit you use.
•
After you clean an optical transceiver, make sure that the connector tip of the
fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning
kit, such as the Opptex Cletop-S Fiber Cleaner. Follow the directions for the cleaning
kit you use.
Replacing an SFP+ Transceiver on JRR200 Route Reflector
Small form-factor pluggable plus transceivers (SFP+) are enhanced SFP transceivers
that provides support for data rates of up to 10 Gbps for fiber-optic or copper interfaces.
You can remove and replace the SFP+ transceivers without powering off the device or
disrupting device functions.

Removing an SFP+ Transceiver
To remove an SFP+ transceiver:
1.
Have ready a replacement transceiver or a transceiver slot plug, an antistatic mat,
and a rubber safety cap for the transceiver.
2.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
3.
Label the cables connected to the transceiver so that you can reconnect them correctly
later.
