Product Overview

The HYTOPTODEVICE GLC-BX-U is a high-performance 1000BASE-BX BIDI SFP module designed for Cisco gigabit network infrastructure. It operates at 1310nm TX / 1490nm RX wavelength, delivers stable 10km transmission over standard single-mode fiber (SMF), and adopts a simplex LC fiber connector for single-fiber bidirectional communication. Fully compliant with IEEE 802.3ah and SFP MSA industry standards, this BIDI optic module greatly saves fiber resources and reduces deployment costs. It is widely used for enterprise campus uplinks, FTTH broadband access, and media converter long-distance interconnection scenarios.

Frequently Asked Questions 

Q1: Is HYTOPTODEVICE GLC-BX-U 100% compatible with original Cisco switches?
A: Yes. All modules pass real Cisco hardware testing with verified compatibility videos available. No firmware changes or manual configuration required, fully plug-and-play.

Q2: What wavelength and transmission distance does GLC-BX-U support?
A: It features 1310nm TX / 1490nm RX wavelength, supporting up to 10km stable transmission over standard single-mode fiber (SMF).

Q3: What fiber type should I use for GLC-BX-U optical module?
A: It only supports single-mode fiber (OS1/OS2 SMF). Multimode fiber cannot reach standard transmission distance and will cause unstable links.

Q4: Does GLC-BX-U need firmware upgrade when installed on Cisco devices?
A: No firmware changes or upgrades needed. Preloaded standard Cisco EEPROM ensures zero-error recognition.

Q5: What paired module is required for GLC-BX-U single-fiber communication?
A: It must be paired with GLC-BX-D (1490nm TX/1310nm RX) to complete bidirectional single-fiber transmission.

Q6: Can this GLC-BX-U module work with non-Cisco mainstream brand switches?
A: Yes. It is 100% compatible with 150+ mainstream network brands including HPE, Juniper, MikroTik, Huawei and more, with real-device test verification.

Q7: What are the advantages of choosing HYTOPTODEVICE GLC-BX-U over Cisco OEM modules?
A: Same performance and full compatibility, more cost-effective pricing, saves brand premium for your project, with professional test video proof and reliable factory support.

Q8: Does this GLC-BX-U transceiver support DDM digital monitoring?
A: Yes, standard DDM function is supported for real-time optical power and temperature monitoring to ensure link stability.

Q9: Can I get testing videos before placing bulk orders?
A: Absolutely. We provide official compatibility testing video proof upon request to eliminate all compatibility concerns.

Q10: Is hot-swap supported for GLC-BX-U during device operation?
A: Yes, HYTOPTODEVICE's standard SFP hot-plug design supports safe hot swapping without shutting down running network devices.
