FAQ
1. What is the GJS-BF072 used for?
The GJS-BF072 is a flat inline fiber optic splice and distribution closure for FTTx access networks. It combines fiber splicing, mid-span access, cable branching, optional optical splitting and connectorized subscriber distribution in one enclosure.
2. What does the inline cable entry design mean?
The main cable ports are positioned on opposite sides of the enclosure, allowing the feeder cable to enter one side and exit the other. Independent branch and drop cable ports provide distribution connections along the feeder route.
3. Does the closure support mid-span access?
Yes. The opposed feeder ports and modular sealing assembly support installation around an uncut feeder cable. This allows technicians to access selected fibers for branching or splicing while leaving the remaining fibers uncut.
4. What is the maximum fiber splice capacity?
The GJS-BF072 accommodates up to 72 single-fiber splices across three splice trays, with up to 24 splices per tray.
5. What cable sizes and entry options are supported?
The closure provides two inline mid-span ports for feeder cables with an outside diameter of Ø 7.5–15 mm, two additional PG16 cable glands, and eight drop cable ports for Ø 6–8 mm cables. Please confirm the cable diameter range of the supplied PG16 glands when selecting your configuration.
6. Does it support SC adapters and PLC splitters?
Yes. The closure supports up to eight SC adapters, with SC/APC as the standard configuration and SC/UPC available as an option. A 1×8 Micro PLC splitter configuration is also available; please confirm the splitter quantity and arrangement for your order.
7. Can the closure be reopened for maintenance or expansion?
Yes. The bolted housing and re-enterable mechanical sealing system allow the closure to be opened for maintenance, additional splicing or subscriber connections. Sealing surfaces and components should be inspected and correctly reassembled whenever the closure is reopened.
8. Does cable sealing require heat-shrink tools?
No. The cable entries use mechanical sealing with rubber grommets, so heat-shrink tools and an open flame are not required for cable sealing.
9. How are unused SC/APC connectors stored?
A dedicated internal parking position holds unused SC/APC connectors and keeps them organized. Keeping the connector dust caps fitted helps protect the ferrules from contamination before connection.
10. Where can the GJS-BF072 be installed?
The closure is intended for aerial, pole and wall installations. Underground use is subject to qualification of the final enclosure and installation configuration. Confirm the required mounting accessories and site conditions before ordering.
11. Is the GJS-BF072 IP68 rated?
IP68 is the current design target. The final ingress-protection rating must be confirmed through testing of the production enclosure. Please request the applicable test documentation before specifying the product for applications that require a verified IP68 rating.
12. What information should I provide when requesting a quotation?
Please provide the feeder and drop cable diameters, required splice capacity, SC adapter type and quantity, PLC splitter requirements, installation method and mounting accessory needs. These details help determine the appropriate product configuration.
