Description

The GLC-ZX-SMD-BCC is a drop-in compatible replacement for the Cisco GLC-ZX-SMD. This 1GB SFP transceiver delivers plug-and-play compatibility with Cisco Gigabit Ethernet switches and routers, providing 1000BASE-ZX connectivity over single-mode fibre. - Complies with IEEE 802.3z 1000BASE-ZX and SFP MSA standards, ensuring interoperability with industry-standard Gigabit Ethernet infrastructure - Operates at 1550nm wavelength over duplex single-mode fibre with LC connectors, reaching up to 70km (link span depends on fibre quality, splices, and connectors) - Provides 21 dB optical link budget with hot-swappable SFP form factor for in-service installation and removal - Supports Digital Optical Monitoring (DOM) per SFF-8472 MSA, enabling real-time monitoring of optical power, temperature, laser bias current, and supply voltage - For shorter single-mode spans under 8 dB loss, a 10 dB inline optical attenuator is required at each end to prevent receiver overload - Compatible with 0 to 70 degrees C commercial temperature environments

Features

• IEEE 802.3z 1000BASE-ZX compliance guarantees interoperability with standards-based Gigabit Ethernet platforms and ensures line-rate 1.25 Gbps serial transmission at 1550nm
• 21 dB link budget supports spans up to 70 km over OS1/OS2 single-mode fibre, with actual reach dependent on cumulative loss from fibre attenuation, splices, and connector quality
• SFF-8472 Digital Optical Monitoring exposes five real-time parameters via I2C interface: transmit power, receive power, temperature, bias current, and supply voltage, with programmable alarm and warning thresholds
• 1550nm DFB laser transmitter paired with PIN photodiode receiver provides low chromatic dispersion penalty and stable optical output across commercial temperature range
• Hot-swappable SFP form factor enables in-service module replacement without disrupting adjacent ports or requiring chassis power-down
• For back-to-back or short-reach single-mode links with less than 8 dB span loss, Cisco specifies a 10 dB inline attenuator at each receiver to prevent front-end saturation
• SFP MSA mechanical and electrical compliance allows deployment in any MSA-conformant Gigabit Ethernet SFP port across vendor platforms

FAQs

Q: Will this work in place of the Cisco GLC-ZX-SMD?
A: Yes. The GLC-ZX-SMD-BCC meets the same 1000BASE-ZX standard, operates at 1550nm over single-mode fibre with an SFP form factor, and provides plug-and-play compatibility with Cisco Gigabit Ethernet platforms that accept the GLC-ZX-SMD.

Q: Which Cisco platforms support this transceiver?
A: This transceiver works in any Cisco switch or router with SFP ports that support 1000BASE-ZX optics, including Catalyst, Nexus, and ISR series. Compatibility is determined by the SFP port specification, not specific model numbers. Verify your platform datasheet lists 1000BASE-ZX or GLC-ZX-SMD support.

Q: Why does Cisco recommend a 10 dB attenuator for short spans?
A: The GLC-ZX-SMD transmits 0 to 5 dBm and the receiver sensitivity is better than negative 24 dBm, yielding a 21 dB link budget designed for long reach. On spans with less than 8 dB total loss, the received signal can exceed the receiver's maximum input power and cause bit errors. A 10 dB attenuator at each receiver end prevents saturation.

Q: What fibre type and connector are required for 70 km reach?
A: You need duplex LC-terminated OS1 or OS2 single-mode fibre (9/125 µm core). Actual reach depends on cumulative loss: at 0.35 dB/km attenuation plus splice and connector losses, 70 km is achievable within the 21 dB budget. Higher quality fibre with lower loss can extend reach slightly; older or higher-loss fibre reduces it.

Q: Can I monitor link health in real time with this module?
A: Yes. The module supports SFF-8472 Digital Optical Monitoring. Your switch or NOS can poll the transceiver's I2C interface to read current transmit power, receive power, temperature, bias current, and supply voltage. These values help diagnose marginal links, dirty connectors, or ageing lasers before they cause outages.

Tested on real vendor hardware in Sydney

Every Blue Cable Co transceiver is coded for your platform and tested in our Sydney test rack on real vendor switches and firewalls before it ships. We check it is recognised and links up the same way the OEM optic does, so you don't find an "unsupported transceiver" error after it's installed.

Brands tested: Cisco, Meraki, Arista, Aruba, HPE, Juniper, Dell, Fortinet, Palo Alto, Check Point, Sophos, Moxa and NVIDIA. Speeds up to 100Gb.
