Projects in the Philippines benefit from keeping the configuration, branch identification and installation requirement consistent across every participating site. The customized duplex FTTA program builds the standard outdoor base station jumper to the particular design of the site: LC or SC connectors in any mix, the measured channel length from a few meters to full tower runs, and armored breakout lengths matched to the hardware at each end. The fiber cable platform is unchanged: two OS2 9/125µm single-mode fibers of Corning G.657.A1 glass in a 7.0mm LSZH outdoor jacket, with helical steel armored branches protecting the tails and a potted, strain-relieved breakout point.

Base station sites differ in every dimension: tower height, shelter mounting point, enclosure type and equipment generation. A customized FTTA jumper takes those dimensions as input. The connector interface mix follows the actual ports on the baseband and radio sides, the length follows the measured channel with working slack, and the armored breakout at each end follows the mounting point where this backbone cable separates into legs. The result installs without adaptors, without a service loop of surplus cable, and without field termination.
The breakout is the point where the 7.0mm trunk divides into two protected legs. A short 0.03m breakout suits a compact enclosure where both connectors sit side by side; the standard 0.34m armored branch reaches separated ports inside a radio shroud or distribution box; a 0.2m intermediate alternative covers layouts in between. Deciding on the right breakout keeps every centimeter of exposed fiber inside the helical steel tube, which is where crush and rodent damage actually happen.
Customization changes the design, not the engineering. The fiber cable retains the 200/400N long and short-term tensile rating for pulling and vertical hanging, the 1100/2200N crush resistance, and the -20 to 70 degree Celsius operating range. G.657.A1 glass keeps the 10D static bend tolerance that congested enclosures demand, and remains compatible with installed G.652.D feeder plant.
For multi-site deployments, the design is recorded once and repeated exactly: connector mix, length, breakout, labeling. Crews at site fifty install the identical cord that was validated at site one, which keeps commissioning time predictable and spares planning simple. The labeling scheme may follow the customer document, with leg identification at both cable ends printed to match the site record.
State the measured channel length with the inquiry, including the tray optical route and working slack at both cable ends; the factory builds to that figure and confirms the manufacturable specification before release to production.
Every customized cord is terminated with precision zirconia ferrule connectors and optically tested as a complete item: insertion loss is verified against the 0.3dB ceiling and return loss against the 50dB minimum on each individual leg. End-face geometry is inspected on each connector interface, and the delivered cord is ready to plug into service without on-site rework.
Send the applicable connector mix, channel length and breakout preference with the inquiry. The factory confirms the manufacturable specification before release to production and keeps the design on record for repeat orders across the rollout. Customers in the Philippines can include multi-site labeling or documentation requirements when requesting a project quotation.
