Manual 013299 Rev C - Oct 2019
Circulator Application
The Cleareld WaveSmart Circulator facilitates economical ber relief (4 strands
to 2 strands) on most legacy Optical Transport system spans equipped with 1310
nm or 1550 nm WBO (Wide Band Optic) SONET/Ethernet optics [Discrete/SFP/
XFP (Small Form Pluggable/ 10g Small Form Pluggable) based] to carry trafc in a
bi-directional format (XMT & RCV) (Transmit and Receive).
Note: SFP/XFP systems may be better served with a WDM solution. See your
Cleareld representative for more information.
Prerequisites:
Verify that system is currently operating within AML/EML (Actual Measured Loss/Expected Measured Loss) limits to
ensure a healthy system.
Verify the optical transport system can accommodate the additional 1.6 dB IL introduced into the span by the inser-
tion of 2 circulators (0.8 dB per circulator).
Verify the laser source is of a SLM DFB (Single-Longitudinal Mode Distributed Feedback) type with adequately
narrow spectral width.
If the system uses an MLM (Multi-Longitudinal Mode) type laser source, ber relief can still be obtained by imple-
menting WDM’s in place of circulators. See your Cleareld representative for more information.

Install a Cleareld MOC cassette containing at least two circulator components into an appropriate Cleareld housing
at either end of the existing span to be treated. (Symmetrical deployment design).
Verify that there is live trafc on the “working” ber pair and not the “protect” ber pair. If the trafc is on the protect
pair, then as appropriate to the individual optical transport system practices, manually switch live trafc away from
protect ber pair to the working pair.
Connect 2 ber jumpers with appropriate connectors from the Optical Transport (SONET/Ethernet) TX (Protect) to
the TX port and RX (Protect) to the RX port of the Cleareld MOC Cassette. Connect them to the ports labeled TX
A/B/C/D & RX A/B/C/D respectively at both ends of the span (A&Z). The letters A, B, C, and D designate the individu-
al circulator components within the MOC. “A” is the rst component. “B” is the second component.
At both ends of the span, connect 1 ber jumper between the OSP ber assigned to remain in-service carrying the
bi-directional optical “Protect” signal to the Port labeled “OUT A/B/C/D” as appropriate on the Cleareld MOC Cas-
sette.

Test and verify signal performance is as expected via Link Loss Budget analysis. Remove or add attenuators as
needed to maintain proper power margin.
Upon successful completion of Step # 5, manually switch the Network Element to “Protect” and verify valid switch via
PM (Performance Monitoring) analysis.
Upon successful completion of Step # 6, perform steps 3-5 as above applied to the TX (Working) and RX (Working)
ber pair.
Upon successful completion of Step # 7 and verication that the “Working” path is properly operating via PM Analy-
sis, manually switch live trafc back to “Working” and retest via PM one last time. Insure that all alarms clear and that
trafc is operating normally.
(Optional) Insert a Near End QRSS (Quasi Random Signal Source) VT/STS (Virtual Tributary/Synchronous Trans-
port Signal) level simulated trafc hard loop at the far end and then monitor the BER during exercise, and/or force a
manually switch to “Protect” to re-conrm proper operation.

Inspect Then Connect
These are Cleareld recommended products/applications. Use the product
you feel will complete your cleaning procedures. Create a “best practice” for
your company and follow those procedures.
The use of Chemtronics end face and bulkhead cleaning products and
techniques ensures a clean end face, no matter the type of contamination.
Before cleaning any connector, be sure you know what type of contaminate
you are cleaning (dry, uidic, or combination). All the available products are
good, it’s the process that you need to be aware of. Using a dry cleaning
method to clean “dirt” can lead to scratching of the end face. Learn the
process of cleaning properly.
Note: It is NOT recommended to use isopropyl alcohol to clean the end face.
Cleaning an SC/LC Connector
Cleaning the End Face
• Place one wiping paper on QbE-2 FiberSafe™ Cleaning Platen.
(Figure 1)
• Apply small amount of precision cleaner (about 1” in diameter) with
Electro-Wash MX pen on to one end of the wipe. (Figure 2)
• Hold end face at a 90 degree angle. For APC connection, adjust by
slightly tilting the container or end face. Angle is correct when no drag is
felt on the end face. (Figure 3)
• Draw end face from wet to dry part of the wipe 3 times. Use just enough
pressure to ensure complete contact between end face and the wipe.
Note: DO NOT retrace previous step.

Connector Cleaning Procedure
Whether factory terminated or eld spliced, clean connectors are essential for proper system operation. Even the smallest
dust particle can cause transmission problems, so for optimal network performance inspect, and if necessary, clean
connectors and adapters prior to mating.

Cleaning the Ferrule
• Lightly moisten the ber optic swab (2.5mm/38542F or 1.25mm/38040)
by spotting a small amount (about 1”) of Electro-Wash PX or
Electro-Wash MX pen onto the QbE. Hold the swab, 1 side down to the
wetted area and hold for a count of 1-2-3-4-5. (Figure 4)

Cleaning the Mate Through an Adapter AND the Adapter Itself
• Lightly moisten the ber optic swab (2.5mm/38542F or 1.25mm/38040)
by spotting a small amount (about 1”) of Electro-Wash PX or
Electro-Wash MX pen onto the QbE. Hold the tip of the swab onto the
wetted area and hold for a count of 1-2-3-4-5.
• Insert the swab into the adapter to the connector, press lightly against
the connector, twist 2-3 times, remove and discard.
• Dry with a second dry swab.
• Inspect, repeat cleaning if necessary, and test for signal strength.
• Use additional swabs to clean inside the actual adapter. Moisten
swab, like above, and insert through hole and remove while twisting.
(Figure 6)
• Insert swab into side of ferrule, wet side to the ceramic ferrule and
circle around 2-3 times and remove. Turn swab to dry side and repeat.

Male Connector
• Use of Chemtronics MTP Connector Cleaning Swabs (CC505F) is rec-
ommended. Even after cleaning with a probe cleaner, you should always
clean the pins with this (or an equivalent) type swab. Cleans ALL MTP/
MPO connector end faces. This swab also cleans the “pins” of the male
connector
• Lightly “spot” a QbE-2 wipe on the platen with Electro-Wash PX Fiber
Optic Cleaner, the FiberWash or MX Pen.
• Lightly touch short side of the MTP/MPO Connector Swab to the wetted
area (3-5 secs) to absorb some cleaning solution (DO NOT over saturate
the swab).
• Wipe connector areas to be cleaned, sliding pad from bottom of pad
across and forward to tip of swab, from 1 side to the other, turn over and
use long side to dry in same movement.
