Cisco Fiber Optic Module GLC-BX40-U-I:
The Cisco Fiber Optic Module GLC-BX40-U-I is a 1 Gigabit Ethernet SFP fiber optic transceiver designed for long-distance single-mode fiber connections using a single strand of fiber. As a BiDi (bi-directional) module, it transmits data at 1310 nm and receives at 1550 nm, allowing simultaneous two-way communication over the same fiber, which reduces fiber cabling requirements.
This Cisco Module uses LC Simplex connectors and supports link distances up to 40 km (25 miles). Compact and hot-swappable, the GLC-BX40-U-I is compatible with Cisco switch and router, making it ideal for enterprise, metro, and fiber-to-the-home (FTTH) networks that need efficient long-range Gigabit connectivity.
This module designed by Cisco company and you can buy it in network equipment market with 1-year Atech warranty. If you want to know more about network module specially cisco fiber optical module, you can contact us.
