Cisco compatible GLC-BX-D-I Description

Cisco compatible GLC-BX-D-I is SFP (Small Form factor Pluggable) Transceiver, operating over Single Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 12 dB, with in most cases is enough to reach about 10 km distance. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. This transceiver use top quality DFB Laser transmitter which operates at nominal wavelength 1490 nm. and PIN Photodiode receiver which operates at 1310 nm. wavelength. As bidirectional (BIDI) single fiber transceiver GLC-BX-D-I (Tx:1490nm Rx:1310nm) transceiver usually works in pair with GLC-BX-U-I (Tx:1310nm Rx:1490nm) transceiver to establish link. Transceiver support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. Cisco compatible GLC-BX-D-I operates in Industrial -40° to 85°C temperature range and has Single LC interface. SFP support 1.063-1.25Gbps data rate and such applications as Gigabit Ethernet (1.25 Gbps), 1G Fiber Channel (1.0625 Gbps). SFP Single Fiber optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Internet Service Provider (ISP) Gigabit Ethernet communication links, Enterprice LAN & SAN Networks, Data Center LAN & SAN Networks and other optical links.

Our version of compatible Cisco GLC-BX-D-I is based on our product BIDI-1.25G-SFP-11-BDI which is CE/RoHS certified and it is Compliant with product safety standards and compliant to SFP Multi Source Agreement SFF-8074 industry standard. To ensure compatibility we have tested our compatible version of Cisco GLC-BX-D-I Transceiver in latest platforms of Cisco networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with Cisco platforms. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP transceiver EEPROM memory data validation tests. We will be glad to know your requirements - Contact Us.
