Q: Are these 1G BiDi transceivers fully compliant with international telecommunications and environmental standards? By S***n on 2026-05-23
A: Yes. The module complies strictly with IEEE 802.3ah 1000BASE-BX, SFF-8472 diagnostic standards, and SFP MSA specifications. It is fully certified under CE, FCC, and RoHS environmental directives, ensuring full compliance for commercial enterprise data center and carrier network deployments. By admin on 2026-05-23
Q: Will the LS-BL55311G-60C work seamlessly in our Cisco Catalyst and Juniper EX switches without throwing unsupported transceiver warnings? By J***s on 2026-02-25
A: Yes, absolutely. The transceiver is fully SFP MSA compliant and can be custom-coded for 100% interoperability with Cisco, Juniper, Arista, MikroTik, Ubiquiti, and other major OEM switch platforms. It enables full DDM/DOM telemetry readout with zero CLI vendor lock-in errors. By admin on 2026-02-25
Q: Our fiber links terminate in unheated outdoor roadside cabinets. Do you offer an industrial wide-temperature version of this 60km module? By K***z on 2026-01-05
A: Yes. While this model (LS-BL55311G-60C) is designed for commercial indoor environments (0℃ to 70℃), we produce an industrial wide-temperature variant (P/N: LS-BL55311G-60I) engineered to operate continuously from -40℃ to 85℃ in harsh outdoor NEMA enclosures. By admin on 2026-01-05
Q: What fiber type is required, and which complementary module do I need on the remote end to close the 60km link? By J***e on 2025-06-14
A: This module requires a single strand of 9/125μm Single-Mode Fiber (OS2 SMF) with a Simplex LC connector. Because this unit transmits at 1550nm and receives at 1310nm (1550TX/1310RX), the remote end must be paired with the complementary 1310nm-TX/1550nm-RX 60km transceiver (P/N: LS-BL31551G-60C) to establish the bidirectional optical circuit.
